DATASHEET IDT2308B 3.3 VOLT ZERO DELAY CLOCK MULTIPLIER Description Features The IDT2308B is a high-speed phase-lock loop (PLL) clock multiplier. It is designed to address high-speed clock distribution and multiplication applications. The zero delay is achieved by aligning the phase between the incoming clock and the output clock, operable within the range of 10 to 133 MHz. * Phase-Lock Loop Clock Distribution for Applications ranging from 10 MHz to 133 MHz operating frequency * Distributes one clock input to two banks of four outputs * Separate output enable for each output bank * External feedback (FBK) pin is used to synchronize the outputs to the clock input The IDT2308B has two banks of four outputs each that are controlled via two select addresses. By proper selection of input addresses, both banks can be put in tri-state mode. In test mode, the PLL is turned off, and the input clock directly drives the outputs for system testing purposes. In the absence of an input clock, the IDT2308B enters power down, and the outputs are tri-stated. In this mode, the device will draw less than 25A. * * * * * * * The IDT2308B is available in six unique configurations for both prescaling and multiplication of the Input REF Clock. (see Available Options table.) Output Skew <200 ps Low jitter <200 ps cycle-to-cycle 1x, 2x, 4x output options (see Available Options table) No external RC network required Operates at 3.3 V VDD Available in 16-pin SOIC and TSSOP packages Available in Commercial and Industrial temperature ranges The PLL is closed externally to provide more flexibility by allowing the user to control the delay between the input clock and the outputs.

Stresses above the ratings listed below can cause permanent damage to the IDT2308B. These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. 2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 3. The maximum package power dissipation is calculated using a junction temperature of 150C and a board trace length of 750 mils. IDTTM 3.3 VOLT ZERO DELAY CLOCK MULTIPLIER 3 IDT2308B REV B 030509 IDT2308B 3.3 VOLT ZERO DELAY CLOCK MULTIPLIER CLOCK MULTIPLIER Zero Delay and Skew Control To close the feedback loop of the IDT2308B, the FBK pin can be driven from any of the eight available output pins. The output driving the FBK pin will be driving a total load of 7 pF plus any additional load that it drives. The relative loading of this output (with respect to the remaining outputs) can adjust the input-output delay. For applications requiring zero input-output delay, all outputs including the one providing feedback should be equally loaded. If input-output delay adjustments are required, use the Output Load Difference Chart to calculate loading differences between the feedback output and remaining outputs. Ensure the outputs are loaded equally, for zero output-output skew.
