PI6C2504
Phase-Locked Loop Clock Driver
with 4 Clock Outputs
Product Description
The PI6C2504 features a low-skew, low-jitter, phase-locked loop
(PLL) clock driver, distributing high-frequency clock signals for
SDRAM and server applications. By connecting the feedback
FB_OUT output to the feedback FB_IN input, the propagation
delay from the CLK_IN input to any clock output will be nearly zero.
Product Features
High-Performance Phase-Locked-Loop Clock
Distribution for Networking
Registered DIMM Synchronous DRAM modules
for server/workstation/PC applications
Allows Clock Input to have Spread Spectrum
modulation for EMI reduction
Zero Input-to-Output delay
Low jitter: Cycle-to-Cycle jitter 100ps max.
On-chip series damping resistor at clock output
drivers for low noise and EMI reduction
Operates at 3.3V V
CC
Wide range of Clock Frequencies up to 80 MHz
Package: Plastic 16-pin QSOP Package (Q)
