4-output CK420BQ Derivative 9SQL4954 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 PCIe Common Clock CC and Independent Reference Clock IR architectures. Recommended Application PCIe Gen1, Gen2, Gen3, Gen4 Server Clock Output Features • 4 -100MHz Low-power HCSL LP-HCSL CPU/SRC pairs • Integrated terminations for Zout • 1 - 3.3V LVCMOS REF output w/Wake-On-LAN WOL support Key Specifications • BCLK outputs • Cycle-to-cycle jitter <50ps • Output-to-output skew <50ps • PCIe Gen1, Gen2, Gen3, Gen4 CC compliant • PCIe Gen2, Gen3 IR compliant • QPI/UPI compliant • SAS12G compliant SSC off • 12k-20M phase jitter <2ps rms SSC off • REF output • Phase jitter <200fs rms SSC off • ±50ppm frequency accuracy on all clocks DATASHEET Features/Benefits • Direct connection to transmission lines saves 16 resistors and 27mm2 compared to standard HCSL • 142mW typical power consumption eases thermal concerns 1/10 the power of CK420BQ • Contains default configuration SMBus interface not required for device operation • OE# pins support BCLK power management • 25MHz input frequency standard crystal frequency • 25MHz REF output eliminates XO from boar • Pin/SMBus selectable 0%, or 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 Block Diagram vOE 3:0 # XIN/CLKIN_25 vSADR vSS_EN_tri SDATA_3.3 SCLK_3.3 Control Logic SSC Capable BCLK3 BCLK2 BCLK1 BCLK0 9SQL4954 NOVEMBER 4, 2016 2016 Integrated Device Technology, Inc. 9SQL4954 DATASHEET Pin Configuration Ordering Information Part / Order Number Shipping Packaging 9SQL4954BNLGI Trays 9SQL4954BNLGI8 Tape and Reel Package 32-pin VFQFPN 32-pin VFQFPN Temperature -40 to +85° C -40 to +85° C Issue Date 10/1/2015 3/7/2016 3/25/2016 Intiator RDW Page # Various Various Updated block diagram Minor corrections to front page text. 1,4, 5/3/2016 RDW Removed Device name from "Termination" table under Test Loads various Updated SMBus Updated electrical tables per PCIe Base Spec 4.0v7 of Oct. 2016 to add PCIe Gen4 CC and PCIe Gen2-3 IR to the data sheet.
