The Direct Rambus clock generator - lite (DRCG-Lite) is an independent crystal clock generator. It performs clock multiplication using PLL, sourced by an internal crystal oscillator. It provides one differential, high-speed Rambus channel compatible output pair. Also, one single-ended output is available to deliver 1/2 of the crystal frequency. The Rambus channel operates at up to 400 MHz with an option to select 300 MHz as well. The desired crystal is a 18.75-MHz crystal in a series resonance fundamental application.
The CDCR61APW is characterized for operation over free-air temperatures of 0°C to 85°C.
