CDCU877RHAR Description

Short technical summary and product information.

The CDCU877RHAR from Texas Instruments is a high-performance, low-jitter, low-skew, zero-delay buffer. It is designed to distribute a single differential clock input to ten differential clock output pairs, making it suitable for DDR II applications.

 

This clock driver operates at 1.8V with a frequency range of 10 MHz to 400 MHz. Key electrical specifications include low static phase offset of ±50 ps, low jitter (cycle-cycle) of ±30 ps, low output skew of 35 ps, and low period jitter of ±20 ps. It also features low dynamic phase offset of ±15 ps and low current consumption of less than 135 mA.

 

The device meets or exceeds the JESD82-8 PLL standard for PC2-3200/4300. It is compatible with spread spectrum clocking for reduced EMI. The CDCU877RHAR includes external feedback pins for synchronizing outputs to the input clocks and fail-safe inputs.

 

Packaged in a 40-VQFN (6x6 mm) with an exposed pad, this component is designed for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C.
