CDCU877ARHAR Description

Short technical summary and product information.

The Texas Instruments CDCU877ARHAR is a high-performance, low-jitter, low-skew, zero-delay buffer designed for DDR II applications. It distributes one differential clock input to ten differential clock outputs and one pair of feedback clock outputs.

 

This clock driver operates at a frequency range of 10 MHz to 400 MHz with a low static phase offset of ±50 ps and low jitter (cycle-cycle) of ±30 ps. It meets or exceeds the JESD82-8 PLL standard for PC2-3200/4300. The device features fail-safe inputs and low current consumption of less than 135 mA.

 

The CDCU877ARHAR is available in a 40-pin VQFN package and operates within an industrial temperature range of -40°C to 85°C. Its surface mount mounting type makes it suitable for various PCB designs.

 

Key electrical characteristics include a 1.8V operating voltage, differential inputs and outputs (SSTL-18), and a 1:10 ratio. The device incorporates a Phase Lock Loop (PLL) for precise clock synchronization.
