CDCV855IPW Description

Short technical summary and product information.

The Texas Instruments CDCV855IPW is a high-performance, low-skew, low-jitter zero delay buffer. It is designed to distribute a differential clock input to four differential clock outputs and one differential feedback clock output pair. This PLL clock driver is suitable for Double Data-Rate Synchronous DRAM applications and is compatible with spread spectrum clocking for reduced EMI.

Key electrical specifications include a core supply voltage range of 2.3V to 2.7V, an operating frequency up to 180 MHz, and an output skew of 50 ps. The device features low jitter of ±50 ps (cycle-to-cycle) and consumes less than 200 µA quiescent current. It supports SSTL-2 input and output standards.

The CDCV855IPW is available in a 28-TSSOP package, designed for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The device includes a low-power mode that is activated when the input clock signal is less than 20 MHz or when the PWRDWN pin is low. An input frequency detection circuit manages the transition into and out of this low-power mode.
