CDCVF855PW Description

Short technical summary and product information.

The CDCVF855PW from Texas Instruments is a high-performance, low-skew, low-jitter, zero-delay buffer designed for DDR memory modules. It distributes a differential clock input to four differential clock output pairs and two feedback clock outputs.

Key electrical specifications include a core supply voltage of 2.5V and an output supply voltage of 1.7V. It boasts low additive RMS jitter of 65 fs (typical), output skew of 40 ps, and cycle-cycle jitter of ±60 ps. The device operates over a frequency range of 60 MHz to 220 MHz and supports SSTL-2 input and output types.

This clock driver is available in a 28-TSSOP package and is suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The CDCVF855PW meets or exceeds JEDEC standards for DDR memory specifications.

Applications include DDR Memory Modules (DDR400/333/266/200) and zero-delay fan-out buffering. The device enters a low-power mode when no clock input signal is applied or when PWRDWN is low.
