Texas Instruments CDCU877ZQLT
- Part Number:
- CDCU877ZQLT
- Manufacturer:
- Texas Instruments
- Ventron No:
- 2971809-CDCU877ZQLT
- Description:
- IC PLL CLOCK DRIVER 1.8V 52-BGA
- ECAD Model:
-
- Datasheet:
- CDCU877(A)
Description
The CDCU877 is a 1.8V 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. The device features low jitter, low skew, and low power consumption. It meets or exceeds the JESD828 PLL standard for PC23200/4300.
Features
1.8V operation
Spread spectrum clock compatible
Operating frequency: 10 MHz to 400 MHz
Low current consumption: <135 mA
Low jitter (cyclecycle): 30 ps
Low output skew: 35 ps
Low period jitter: 20 ps
Low dynamic phase offset: ±15 ps
Low static phase offset: 150 ps
Distributes one differential clock input to ten differential outputs
External feedback pins (FBIN, FBIN) for synchronization
Meets or exceeds JESD828 PLL standard for PC23200/4300
Failsafe inputs
Applications
DDR II memory systems
Graphics cards
Networking equipment
Highspeed data transmission
