2.5V or 3.3V, 200MHz, 11 Output Zero Delay Buffer
Features
The PCS5I9352 features an LVCMOS reference clock
•
Output frequency range: 16.67MHz to 200MHz
input and provides 11 outputs partitioned in 3 banks of 5, 4,
•
Input frequency range: 16.67MHz to 200MHz
•
2.5V or 3.3V operation
•
Split 2.5V/3.3V outputs
•
± 2% max Output duty cycle variation
1:3. Each LVCMOS compatible output can drive 50Ω series
•
11 Clock outputs: Drive up to 22 clock lines
or parallel terminated transmission lines. For series
•
LVCMOS reference clock input
terminated transmission lines, each output can drive one or
•
125-pS max output-output skew
two traces giving the device an effective fanout of 1:22.
•
PLL bypass mode
•
Spread AwareTM
•
Output enable/disable
to run between 200MHz to 500MHz. This allows a wide
•
Pin compatible with MPC9352 and MPC952
range of output frequencies from 16.67MHz to 200MHz.
•
Industrial temperature range: -40°C to +85°C
For normal operation, the external feedback input, FB_IN,
•
32-Pin 1.0mm TQFP & LQFP Packages
is connected to one of the outputs. The internal VCO is
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
The PLL is ensured stable given that the VCO is configured
running at multiples of the input reference clock set by the
feedback divider, see Table 1.
Functional Description
The PCS5I9352 is a low voltage high performance 200MHz
PLL-based zero delay buffer designed for high speed clock
When PLL_EN# is HIGH, PLL is bypassed and the
distribution applications.
reference clock directly feeds the output dividers. This
mode is fully static and the minimum input clock frequency
specification does not apply.

Note: 1. PD = Internal pull-down.
2.A 0.1µF 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
supply pins.
