IDT, Integrated Device Technology Inc 9SQL4954BNLGI8

Description
The 9SQL4954 is a member of IDT's 'Lite' family of server clocks. It generates 4 100MHz outputs that exceed the requirements of the CK420BQ CPU/SRC clocks. Each output has its own OE# pin for clock management and supports 2 different spread spectrum levels in addition to spread off. It also provides a copy of the 25MHz internal XO. The 9SQL4954 supports PCle Common Clock (CC) and Independent Reference Clock (IR) architectures.

Features
4-100MHz Low-power HCSL (LP-HCSL) CPU/SRC pairs
Integrated terminations for 850 Zout
1-3.3V LVCMOS REF output w/Wake-on-LAN (WOL) support
Cycle-to-cycle jitter <50ps
Output-to-output skew <50ps
PCle Gen1, Gen2, Gen3, Gen4 CC compliant
PCle Gen2, Gen3 IR compliant
QPI/UPI compliant
SAS12G compliant (SSC off)
12k-20M phase jitter <2ps rms (SSC off)
Phase jitter <200fs rms (SSC off)
±50ppm frequency accuracy on all clocks
OE# pins; support BCLK power management
25MHz input frequency; standard crystal frequency
25MHZ REF output; eliminates XO from board
Pin/SMBus selectable 0 %, -0.25% or -0.5% spread on DIF outputs; minimize EMI and phase jitter for each application
BCLK outputs blocked until PLL is locked; clean system start-up
Two selectable SMBus addresses; multiple devices can easily share an SMBus segment
Space saving 32-pin 5x5mm VFQFPN; minimal board space

Applications
PCle Gen1, Gen2, Gen3, Gen4 Server Clock
