Texas Instruments CDCU877BZQLT
- Part Number:
- CDCU877BZQLT
- Manufacturer:
- Texas Instruments
- Ventron No:
- 2983488-CDCU877BZQLT
- Description:
- IC PLL CLOCK DRIVER 1.8V 52-BGA
- ECAD Model:
-
- Datasheet:
- CDCU877B
Description
The CDCU877B is a 1.8-V phase lock loop (PLL) clock driver designed for double data rate (DDR II) applications. It distributes a differential clock input pair to ten differential clock outputs and one differential feedback clock output. The clock outputs are controlled by the input clocks, feedback clocks, LVCMOS control pins, and analog power input.
Features
1.8-V operation
Operating frequency: 10 MHz to 340 MHz
Low current consumption: <115 mA
Low jitter (cycle-cycle): ±30 ps
Low output skew: 25 ps
Low period jitter: 20 ps
Low dynamic phase offset: ±15 ps
Low static phase offset: 150 ps
Spread spectrum clock compatible
External feedback pins for synchronization
Fail-safe inputs
Applications
DDR II memory systems
High-speed data transmission
