The PCK953 is a 3.3 V compatible, PLL-based clock driver device targeted for high performance clock tree designs. With output frequencies of up to 125 MHz, and output skews of 100 ps, the PCK953 is ideal for the most demanding clock tree designs. The devices employ a fully differential PLL design to minimize cycle-to-cycle and phase jitter.
The PCK953 has a differential LVPECL reference input, along with an external feedback input. These features make the PCK953 ideal for use as a zero delay, low skew fanout buffer. The device performance has been tuned and optimized for zero delay performance. The MR/OE input pin will reset the internal counters and 3-State the output buffers when driven HIGH.
The PCK953 is fully 3.3 V compatible and requires no external loop filter components. All control inputs accept LVCMOS or LVTTL compatible levels, while the outputs provide LVCMOS levels with the ability to drive terminated 50 W transmission lines. For series terminated 50 W lines, each of the PCK953 outputs can drive two traces, giving the device an effective fanout of 1:18. The device is packaged in a 7 × 7 mm 32-lead LQFP package to provide the optimum combination of board density and performance.
