ProXO+ Programmable TCXOs

Renesas Electronics Corporation has expanded its robust timing solutions portfolio with the ProXO+ family of compact, ultra-low noise, temperature-controlled clock oscillators. These new ProXO+ Programmable TCXOs deliver ±3ppm frequency stability from -40˚C to +85˚C temperature range and 135fs phase jitter performance. The products from this portfolio are available in an 8-pin plastic package (3.2 x 2.5 mm) and feature programmable frequencies up to 2.1GHz. These differential oscillators are best suited for fiber optic transceiver modules, accelerator cards, smart NIC cards, and networking equipment applications.


Moreover, The ProXO+ family can be combined with Renesas’ complementary clock buffers, power, and microcontroller offerings to create comprehensive solutions for a variety of applications, such as the Xilinx Kintex-7 Power and Timing, the CC-Link IE TSN, and the System on Module (SoM) Solution with RZ/G2E.
