CDCFR83ADBQR Description

Short technical summary and product information.

The Texas Instruments CDCFR83ADBQR is a Direct Rambus clock generator (DRCG) that provides essential clock signals for Direct Rambus memory subsystems. It is designed to synchronize the Direct Rambus channel clock with an external system or processor clock, enabling synchronous communication between the Rambus channel and ASIC clock domains.

This device features a 533-MHz differential clock source, supporting an 1066-MHz data transfer rate for Direct Rambus memory systems. It operates from a single 3.3V supply and consumes approximately 120 mW at 300 MHz. The CDCFR83ADBQR includes features like fail-safe power-up initialization, independent channel clocking, and spread spectrum clocking for reduced EMI.

Designed for use in desktop, workstation, server, and mobile PC motherboards, the CDCFR83ADBQR is packaged in a 24-SSOP (Shrink Small-Outline Package). It supports an industrial operating temperature range of -40°C to 85°C, making it suitable for a broad range of Direct Rambus memory applications. The device also supports frequency multipliers and has no external components required for its Phase-Locked Loop (PLL).
