CDCU877RHAT Description

Short technical summary and product information.

The Texas Instruments CDCU877RHAT is a high-performance, low-jitter, low-skew, zero-delay buffer designed to distribute a differential clock input to ten differential clock outputs. Operating at 1.8V, this PLL clock driver is suitable for DDR II applications.

Key electrical specifications include a maximum operating frequency of 400MHz, a 1:10 input-to-output ratio, and SSTL-18 input/output signaling. It features low static and dynamic phase offset, low jitter (cycle-to-cycle and period), and low output skew, ensuring signal integrity. The device operates within a temperature range of -40°C to 85°C.

Packaged in a 40-VQFN (6x6) with exposed pad, the CDCU877RHAT is designed for surface mount applications. Its main purpose is for memory and DDR2 systems, providing reliable clock distribution.

This clock driver meets or exceeds the JESD82-8 PLL standard for PC2-3200/4300. It also supports spread spectrum clocking for reduced EMI.
