Pin Description
Product Features
High Performance Phase-Locked Loop Clock Distribution for
Synchronous DRAM, server and networking applications.
Zero Input-to-Output delay: Distribute One Clock Input
to four banks of four outputs, with separate output enables
for each bank.
Allow Clock Input to have Spread Spectrum modulation for
EMI reduction. The clock outputs track the Clock Input
modulation.
Maximum clock frequency of 150 MHz.
Low jitter: Cycle-to-Cycle jitter ±100ps max
Operates at 3.3V V
CC
Available Packaging:
48-pin TSSOP (Thin Shrink Small Outline) (A)
Description
The PI6C2516 family is a low-skew, low jitter, phase-locked loop
(PLL) clock driver, distributing high-frequency clock signals for
SDRAM, server and networking applications. By connecting the
feedback FB_OUT output to the feedback FB_IN input, the propa-
gation delay from the CLK input to any clock output will be nearly
zero. This zero-delay feature allows the CLK input clock to be
distributed, providing 4 banks of four outputs.
For test purposes, the PLL can be bypassed by strapping the AV
CC
to ground.
The PI6C2516 family has the same pinout as the TI CDC2516, with
the added feature of allowing Spread Spectrum clock input.
