2-output 3.3V PCIe Clock Generator
9FGL02
DATASHEET
Description
The 9FGL02 devices are 3.3V members of IDT's 3.3V
Full-Featured PCIe family. The devices have 2 output enables
for clock management and support 2 different spread
spectrum levels in addition to spread off. The 9FGL02
supports PCIe Gen1-4 Common Clocked architectures (CC)
and PCIe Separate Reference no-Spread (SRnS) and
Separate Reference Independent Spread (SRIS) clocking
architectures. The 9FGL02P1 can be programmed with a
user-defined power up default SMBus configuration.
Recommended Application
PCIe Gen1-4 clock generation for Riser Cards, Storage,
Networking, JBOD, Communications, Access Points
Output Features
• 2 – 100 MHz Low-Power HCSL (LP-HCSL) DIF pairs
• 9FGL0241 default ZOUT = 100
• 9FGL0251 default ZOUT = 85
• 9FGL02P1 factory programmable defaults
• 1 - 3.3V LVCMOS REF output w/Wake-On-LAN (WOL)
support
• Easy AC-coupling to other logic families, see IDT
application note AN-891
Key Specifications
• PCIe Gen1-2-3-4 CC-compliant
• PCIe Gen2-3 SRIS-compliant
• DIF cycle-to-cycle jitter <50ps
• DIF output-to-output skew <50ps
• DIF 12k-20M phase jitter is <2ps rms when SSC is off
• REF phase jitter is <300fs rms (SSC off) and < 1.5ps RMS
(SSC on)
• ±100ppm frequency accuracy on all clocks
Block Diagram
Features/Benefits
• Direct connection to 100 (xx41) or 85 (xx51)
transmission lines; saves 8 resistors compared to standard
PCIe devices
• 112mW typical power consumption (@3.3V); eliminates
thermal concerns
• SMBus-selectable features allows optimization to customer
requirements:
• control input polarity
• control input pull up/downs
• slew rate for each output
• 33, 85 or 100Ω output impedance for each output
• spread spectrum amount
• input frequency
• 41 and 51 devices contain default configuration; SMBus
interface not required for device operation
• P1 device allows factory programming of customer-defined
input/output frequencies and SMBus power up default;
allows exact optimization to customer requirements
• OE# pins; support DIF power management
• 8MHz - 40MHz input frequency with 9FGL02P1 device
(25MHz default); flexibility
• Pin/SMBus selectable 0%, -0.25% or -0.5% spread on DIF
outputs; minimize EMI and phase jitter for each application
• DIF outputs blocked until PLL is locked; clean system
start-up
• Two selectable SMBus addresses; multiple devices can
easily share an SMBus segment
• Space saving 24-pin 4x4mm VFQFPN; minimal board

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the 9FGL02. These ratings, which are standard values
for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions
above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended
operating temperature range.
