This allows a wide range of output frequencies from 16.67MHz to 200MHz. For normal operation, the external feedback input, FB_IN, is connected to one of the outputs. The internal VCO is running at multiples of the input reference clock set by the feedback divider, see Table 1. The PCS5I9352 features an LVCMOS reference clock input and provides 11 outputs partitioned in 3 banks of 5, 4, and 2 outputs. Bank A divides the VCO output by 4 or 6 while Bank B divides by 4 and 2 and Bank C divides by 2 and 4 per SEL(A:C) settings, see Table 2. These dividers allow output to input ratios of 3:1, 2:1, 3:2, 1:1, 2:3, 1:2, and 1:3. Each LVCMOS compatible output can drive 50Ω 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 1:22. Functional Description The PCS5I9352 is a low voltage high performance 200MHz PLL-based zero delay buffer designed for high speed clock distribution applications. When PLL_EN# is HIGH, 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.
