The 9DBU0441AKILFT is a member of IDT's 1.5 V Ultra-Low-Power (ULP) PCIe family. It has integrated output terminations providing Zo=100 ohms for direct connection to 100 ohm transmission lines. The device has 4 output enables for clock management, and 3 selectable SMBus addresses.
Feature
-
Direct connection to 100 ohm transmission lines; saves 16 resistors compared to standard HCSL outputs
-
45 mW typical power consumption in PLL mode; minimal power consumption
-
Spread spectrum (SS) compatible; allows use of SS for EMI reduction
-
OE# pins; support DIF power management
-
HCSL compatible differential input; can be driven by common clock sources
-
Programmable slew rate for each output; allows tuning for various line lengths
-
Programmable output amplitude; allows tuning for various application environments
-
Pin/software selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
-
Outputs blocked until PLL is locked; clean system start-up
-
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 5x5 mm 32-pin VFQFPN; minimal board space
-
Selectable SMBus addresses; multiple devices can easily share an SMBus segment
