19-0813; Rev 2; 12/10 KIT ATION EVALU E L B AVAILA DVI/HDMI TMDS FR-4 and Cable Equalizer/Driver The MAX3814 TMDSTM EQ/driver IC compensates for FR-4 and cable losses up to the DVITM/HDMI(R) transmit connector and provides a fully compliant DVI/HDMI TMDS output. The device can also be used in DVI/HDMI cable applications to extend reach and improve jitter margin of cable channels at the receive-side connector. The on-chip TMDS drivers operate at a standard current level for implementing a typical DVI/HDMI nonback-terminated transmitter, as well as a 50% higher current mode for using a 200 back termination resistor (nonmatching) to achieve a 10dB return loss. Typical DVI/HDMI output drivers contribute to reflection problems between the connector and a typical highimpedance (open) DVI/HDMI Tx output. The selectable output current (LEVEL pin) gives the option of partial back termination (e.g., differentially connected 200) to mitigate the reflection problem effectively while keeping common-mode offset to a minimum. The 4-channel implementation treats all channels identically. To allow board layout flexibility for DVI and HDMI connectors, which have different channel order, the clock and data channels can be arbitrarily assigned. The MAX3814 operates from a 3.3V power supply, standard for DVI/HDMI applications, and is packaged in a 5mm x 5mm x 0.1mm, 32-pin TQFP package.

It consists of four differential CML input buffers, four independent fixed equalizers, four limiting amplifiers, and four differential CML output buffers (Figure 1). The MAX3814 functions both as an equalizer and as a driver. As an equalizer the MAX3814 automatically adjusts for attenuation levels up to 16dB at 825MHz from either dielectric board losses or skin-effect losses in copper cable. INA+/- INB+/- INC+/- IND+/- TERMINATED TO VCC TERMINATED TO VCC TERMINATED TO VCC TERMINATED TO VCC As a driver the MAX3814 provides CML outputs. The CML output is normally open (i.e., no back termination) and is DC-coupled by transmission line to a termination at the far end per DVI/HDMI standards. The MAX3814 provides nominally 10mA output-switching currents. However, with the MAX3814, there is a selectable higher current drive to accommodate a differential 200 back termination resistor while maintaining the differential swing of 1000mVP-P. This 200 back termination resistor serves to dampen signal reflections returning to the device from discontinuities in the channel such as DVI or HDMI connectors, providing a 10dB return loss. See the CML Inputs and Outputs section for more information.

Functional Diagram _______________________________________________________________________________________ 7 MAX3814 Detailed Description MAX3814 DVI/HDMI TMDS FR-4 and Cable Equalizer/Driver CML Inputs and Outputs The input buffers and the output drivers are currentmode logic (CML). See Figures 2, 3, and 4. The input buffers consist of a 50 load resistor connected to VCC and the input connected to a differential equalizer. The output drivers are open-collector. The current in these outputs can be adjusted to 10mA or 15mA with the control pin LEVEL. For 10mA operation, each opencollector output drives through a transmission line to a 50 pullup of the next stage, as shown in Figure 3. For recommended 15mA operation, the two outputs are bridged by an external 200 back termination resistor that is subsequently pulled up by a 50 resistor of the next stage, as shown in Figure 4. The ESD structure permits signals to achieve 5.5V absolute maximum ratings, high common-mode range, and compatibility to HDMI testing. The back termination resistor should be placed as close as possible to the MAX3814 in the layout. The ESD protection for both the input and output circuitry consists of diodes connected to a transient voltage suppressor clamp shown as a Schottky diode in Figures 2, 3, and 4. For more information about the function of the suppressor clamp, refer to the Detailed Description section of the MAX3208E data sheet (www.maxim-ic.com/MAX3208E).

Simplified Output Circuit with Back Termination Resistor Output Enable Control The ENABLE pin is an LVTTL input that allows the user to shut off the output-collector currents, thereby reducing power consumption of the device. Forcing this pin high turns the output currents off; forcing this pin low (normal operation) turns the currents on. Figure 5 shows a simplified circuit for both the output and enable controls. Figure 5. Simplified Input Circuitry for Output Level (LEVEL) and Enable (ENABLE) Control Applications Information Figure 6a shows a typical TMDS channel from a graphics board of a laptop computer to a remote display. Maintaining a 100 differential impedance for this channel has its challenges. Besides proper board layout of traces, there are multiple reflection points (A to H). For example, at interface F in Figure 6a, a circular arrow shows a reflection at the connector of a remote display. When these reflections hit another interface, they reflect again and thus become echoes corrupting the incident signal. In Figure 6b, the MAX3814 is used to equalize losses, isolate reflections, and redrive the transmission line with high fidelity. _______________________________________________________________________________________ 9 MAX3814 DVI/HDMI TMDS FR-4 and Cable Equalizer/Driver Laptop PC TMDS Equalizer and Driver As shown at location XX in Figure 6b, the MAX3814 equalizes trace losses and redrives the TMDS outputs at the docking connector. The 200 resistor at the output of the MAX3814 absorbs reflections from the docking connector. Dock or Port Expander The MAX3814 can also be used on the dock or port expander as it equalizes loss, isolates the connector, and redrives TMDS output signals at location YY as shown in Figure 6b. Similarly, with the previous applica- LAPTOP tion, the 200 resistor at the output of the MAX3814 absorbs reflections in this case from the DVI or the HDMI connector. An optional 2dB to 6dB attenuator pad can be used to absorb reflections between internal interface connections. If used, the attenuator pad must be a matched Pi or T attenuator network. The resulting flat through loss can be made by the excellent input sensitivity of the MAX3814 as shown in the Typical Application Circuits. The MAX3814's excellent input sensitivity allows the attenuated signal to be restored.

Input and output data channel designations are only a guide. Polarity assignments can be swapped and channel paths can be interchanged. * An uninterrupted ground plane should be positioned beneath the high-speed I/Os. * Ground-path vias should be placed close to the IC and the input/output interfaces to allow a return current path to the IC and the DVI and HDMI inputs. * Maintain a 100 differential transmission line impedance into and out of the MAX3814. * To minimize possible reflections, choose the 200 back termination option. Place this resistor as close to the MAX3814 as possible. Layout Considerations The TMDS CML inputs are the most critical paths for the MAX3814 and great care should be taken to minimize discontinuities on these transmission lines between the connector and the IC. Here are some suggestions for maximizing the performance of the MAX3814. * The data and clock inputs should be wired directly between the cable connector and IC without stubs. * Use good high-frequency layout techniques and multilayer boards with an uninterrupted ground plane to minimize EMI and crosstalk. Refer to the schematic and board layers of the MAX3814EVKIT.

It can equalize cable lengths of 15 meters of 26 AWG wire and 12 meters of 28 AWG wire. Again, the 200 resistor placed at the output of the MAX3814 absorbs reflections from the imperfect termination of the ASIC or imperfect transmission-line interconnect.
