CDCU877AZQLR Description

Short technical summary and product information.

The Texas Instruments CDCU877AZQLR is a high-performance, low-jitter, low-skew, zero-delay buffer that distributes a differential clock input pair to ten differential pairs of clock outputs and one differential pair of feedback clock outputs. It operates at a frequency range of 10 MHz to 400 MHz with a low static phase offset of ±50 ps and low output skew of 35 ps.

 

This clock driver features a 1.8V operating voltage and supports SSTL-18 input and output standards. It is designed for DDR II applications and meets or exceeds the JESD82-8 PLL Standard for PC2-3200/4300. The device includes fail-safe inputs and is compatible with spread spectrum clocking for reduced EMI.

 

The CDCU877AZQLR is available in a 52-Ball MicroStar Junior BGA package with a 0.65-mm pitch. It operates within an industrial temperature range of -40°C to 85°C. The device offers low current consumption of less than 135 mA and includes control pins for output enable and select functions.
