Overview
Description
The 9FGU0241 is a member of IDT's 1.5 V Ultra-Low-Power PCIe clock family with integrated output terminations providing Zo=100 Ω. The device has 2 output enables for clock management, 2 different spread spectrum levels in addition to spread off, and 2 selectable SMBus addresses.
Features
-
Direct connection to 100ohm transmission lines; saves 16 resistors compared to standard PCIe devices
-
23 mW typical power consumption; reduced thermal concerns
-
OE# pins; support DIF power management
-
Programmable slew rate for each output; allows tuning for various line lengths
-
Programmable output amplitude; allows tuning for various application environments
-
DIF outputs blocked until PLL is locked; clean system start-up
-
Selectable 0%, -0.25% or -0.5% spread on DIF outputs; reduces EMI
-
External 25 MHz crystal; supports tight ppm with 0 ppm synthesis error
-
Configuration can be accomplished with strapping pins; SMBus interface not required for device control
-
3.3 V tolerant SMBus interface works with legacy controllers
-
Space saving 4x4mm 24-pin VFQFPN; minimal board space
-
Selectable SMBus addresses; multiple devices can easily share an SMBus segment
