Functional Description
The ASM5I9352 is a low voltage high performance
200MHz PLL-based zero delay buffer designed for high
speed clock distribution applications.
The ASM5I9352 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 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 1:22.
The PLL is ensured stable given that the VCO is configured
to run between 200 MHz to 500 MHz. This allows a wide
range of output frequencies from 16.67 MHz to 200 MHz.
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.
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.
