Overview
Description
The RC2121 family of devices are high-performance programmable clock generators with added diagnostic features to support automotive applications. These RC2121 clock generators are ISO 9001 compliant, AEC-Q100 qualified, can function in the temperature range of -40 °C to 105 °C (Grade 2 equivalent), and provide support for the production part approval process (PPAP).
Features
- 169fs RMS phase jitter (12kHz to 20MHz, 156.25MHz)
- PCIe® Gen6 Common Clock (CC) 27fs RMS
- PCIe SRIS and SRNS support
- 1kHz to 650MHz (differential) and 1kHz to 200MHz (single-ended) outputs
