ISL59910, ISL59913 (R) Data Sheet December 15, 2006 Triple Differential Receiver/Equalizer Features The ISL59910 and ISL59913 are triple channel differential receivers and equalizers. They each contain three high speed differential receivers with five programmable poles. The outputs of these pole blocks are then summed into an output buffer. The equalization length is set with the voltage on a single pin. The ISL59910 and ISL59913 output can also be put into a high impedance state, enabling multiple devices to be connected in parallel and used in multiplexing application. * 150MHz -3dB bandwidth The gain can be adjusted up or down on each channel by 6dB using its VGAIN control signal. In addition, a further 6dB of gain can be switched in to provide a matched drive into a cable. The ISL59910 and ISL59913 have a bandwidth of 150MHz and consume just 108mA on 5V supply. A single input voltage is used to set the compensation levels for the required length of cable. The ISL59910 is a special version of the ISL59913 that decodes syncs encoded onto the common modes of three pairs of CAT-5 cable by the EL4543. (Refer to the EL4543 datasheet for details.) The ISL59910 and ISL59913 are available in a 28 Ld QFN package and are specified for operation over the full -40C to +85C temperature range.

The logic circuits all have a nominal threshold of 1.1V above the potential of the logic reference pin (VREF). In most applications it is expected that this chip will run from a +5V, 0V, -5V supply system with logic being run between 0V and +5V. In this case the logic reference voltage should be tied to the 0V supply. If the logic is referenced to the -5V rail, then the logic reference should be connected to -5V. The logic reference pin sources about 60A and this will rise to about 200A if all inputs are true (positive). The logic inputs all source up to 10A when they are held at the logic reference level. When taken positive, the inputs sink a current dependent on the high level, up to 50A for a high level 5V above the reference level. The logic inputs, if not used, should be tied to the appropriate voltage in order to define their state. Control Reference and Signal Reference Analog control voltages are required to set the equalizer and contrast levels. These signals are voltages in the range 0V to 1V, which are referenced to the control reference pin. It is expected that the control reference pin will be tied to 0V and the control voltage will vary from 0V to 1V. It is; however, acceptable to connect the control reference to any potential between -5V and 0V to which the control voltages are referenced. The control voltage pins themselves are high impedance. The control reference pin will source between 0A and 200A depending on the control voltages being applied. 9 50 75 85 100 125 150 AMBIENT TEMPERATURE (C) AMBIENT TEMPERATURE (C) FIGURE 23. PACKAGE POWER DISSIPATION vs AMBIENT TEMPERATURE 25 FIGURE 24. PACKAGE POWER DISSIPATION vs AMBIENT TEMPERATURE The control reference and logic reference effectively remove the necessity for the 0V rail and operation from 5V (or 0V and 10V) only is possible. However we still need a further reference to define the 0V level of the single ended output signal. The reference for the output signal is provided by the 0V pin. The output stage cannot pull fully up or down to either supply so it is important that the reference is positioned to allow full output swing. The 0V reference should be tied to a 'quiet ground' as any noise on this pin is transferred directly to the output. The 0V pin is a high impedance pin and draws DC bias currents of a few A and similar levels of AC current. Equalizing When transmitting a signal across a twisted pair cable, it is found that the high frequency (above 1MHz) information is attenuated more significantly than the information at low frequencies. The attenuation is predominantly due to resistive skin effect losses and has a loss curve which depends on the resistivity of the conductor, surface condition of the wire and the wire diameter. For the range of high performance twisted pair cables based on 24awg copper wire (CAT-5 etc). These parameters vary only a little between cable types and in general cables exhibit the same frequency dependence of loss. (The lower loss cables can be compared with somewhat longer lengths of their more lossy brothers.) This enables a single equalizing law equation to be built into the ISL59913. With a control voltage applied between pins VCTRL and VREF, the frequency dependence of the equalization is shown in Figure 8. The equalization matches the cable loss up to about 100MHz. Above this, system gain is rolled off rapidly to reduce noise bandwidth. The roll-off occurs more rapidly for higher control voltages, thus the system (cable + equalizer) bandwidth reduces as the cable length increases. This is desirable, as noise becomes an increasing issue as the equalization increases. FN6406.0 December 15, 2006 ISL59910, ISL59913 2 BLUE CM OUT (CH A) VOLTAGE (0.5V/DIV) By varying the voltage between pins VGAIN and VREF, the gain of the signal path can be changed in the ratio 4:1. The gain change varies almost linearly with control voltage. For normal operation it is anticipated the X2 mode will be selected and the output load will be back matched. A unity gain to the output load will then be achieved with a gain control voltage of about 0.35V. This allows the gain to be trimmed up or down by 6dB to compensate for any gain/loss errors that affect the contrast of the video signal. Figure 26 shows an example plot of the gain to the load with gain control voltage. an internal logic decoding block to provide Horizontal and Vertical sync output signals (HOUT and VOUT).

VARIATION OF GAIN WITH GAIN CONTROL VOLTAGE Common Mode Sync Decoding The ISL59910 features common mode decoding to allow horizontal and vertical synchronization information, which has been encoded on the three differential inputs by the EL4543, to be decoded. The entire RGB video signal can therefore be transmitted, along with the associated synchronization information, by using just three twisted pairs. NOTE: Level `Mid' is halfway between `High' and `Low' Power Dissipation The ISL59910 and ISL59913 are designed to operate with 5V supply voltages. The supply currents are tested in production and guaranteed to be less than 39mA per channel. Operating at 5V power supply, the total power dissipation is: V OUTMAX PD MAX = 3 x 2 x V S x I SMAX + ( V S - V OUTMAX ) x ---------------------------R L Decoding is based on the EL4543 encoding scheme, as described in Figure 26 and Table 1. The scheme is a three-level system, which has been designed such that the sum of the common mode voltages results in a fixed average DC level with no AC content. This eliminates the effect of EMI radiation into the common mode signals along the twisted pairs of the cable where: The common mode voltages are initially extracted by the ISL59910 from the three input pairs. These are then passed to * IMAX = Maximum quiescent supply current per channel = 39mA (EQ. 1) * PDMAX = Maximum power dissipation * VS = Supply voltage = 5V * VOUTMAX = Maximum output voltage swing of the application = 2V RL = Load resistance = 150 (EQ. 2) PD MAX = 1.29W JA required for long term reliable operation can be calculated. This is done using Equation 3: 10 FN6406.0 December 15, 2006 ISL59910, ISL59913 Where ( Tj - Ta ) JA = ----------------------- = 50.4CW PD (EQ. 3) Tj is the maximum junction temperature (+150C) Ta is the maximum ambient temperature (+85C) For a QFN 28 package in a properly layout PCB heatsinking copper area, +37C/W JA thermal resistance can be achieved. To disperse the heat, the bottom heatspreader must be soldered to the PCB. Heat flows through the heatspreader to the circuit board copper then spreads and converts to air. Thus the PCB copper plane becomes the heatsink. This has proven to be a very effective technique. A separate application note details the 28 Ld QFN. PCB design considerations are available.
