Industrial temperature range: -40C to +85C 32-pin 1.0mm TQFP & LQFP Packages
PCS5I9350
The PCS5I9350 features Xtal and LVCMOS reference clock inputs and provides nine outputs partitioned in four banks of 1, 1, 2, and 5 outputs. Bank A divides the VCO output by 2 or 4 while the other banks divide by 4 or 8 per SEL(A:D) settings, see Table 2. These dividers allow output to input ratios of 16:1, 8:1, 4:1, and 2:1. Each LVCMOS compatible output can drive 50 series or parallel terminated transmission lines. For series terminated transmission lines, each output can drive one or two traces giving the device an effective fanout of 1:18. The PLL is ensured stable given that the VCO is configured to run between 200MHz to 500MHz. This allows a wide range of output frequencies from 25MHz to 200MHz. The internal VCO is running at multiples of the input reference clock set by the feedback divider, see Table 1. When PLL_EN is LOW, PLL is bypassed and the reference clock directly feeds the output dividers. This mode is fully static and the minimum input clock frequency specification does not apply. low-voltage high-performance
Functional Description
The PCS5I9350 is a
200MHz PLL-based clock driver designed for high speed clock distribution applications.

Note: 1. PU = Internal pull-up, PD = Internal pull-down. 2. A 0.1F bypass capacitor should be placed as close as possible to each positive power pin (<0.2"). If these bypass capacitors are not close to the pins their high frequency filtering characteristics will be cancelled by the lead inductance of the traces. 3. AVDD and VDD pins must be connected to a power supply level that is at least equal or higher than that of VDDQB, VDDQC, and VDDQD output power supply pins.
