PCS5I9773

The ASM5I9773 features one LVPECL and two LVCMOS

reference clock inputs and provides 12 outputs partitioned

in three banks of four outputs each. Each bank divides the

VCO output per SEL(A:C) settings (see Table 2. Function

Table (Configuration Controls)). These dividers allow

output-to-input ratios of 8:1, 6:1, 5:1, 4:1, 3:1, 8:3, 5:2, 2:1,

5:3, 3:2, 4:3, 5:4, 1:1, and 5:6. 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 1:24.

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 8MHz to 200MHz.

For normal operation, the external feedback input FB_IN is

connected to the feedback output FB_OUT. The internal

VCO is running at multiples of the input reference clock set

by the feedback divider (see Table 1. Frequency Table).

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
