Ultra-low-noise clock oscillators offer tight frequency stability

Renesas Electronics Corp. has expanded its timing solutions portfolio with the ProXO+ family of temperature-controlled clock oscillators, targeting high-performance communications and data-center applications. Offering high accuracy and high frequency, these ultra-low-noise clock oscillators are best suited for fiber-optic transceiver modules, accelerator cards, smart NIC cards, and networking equipment applications.

The ProXO+ ultra-low-noise clock oscillators offer tight stability, excellent jitter performance, and high output frequency. The devices provide +/-3 ppm frequency stability over the -40°C to 85°C temperature range with programmable frequencies up to 2.1 GHz, and 135 fs jitter performance (12 KHz to 20 MHz). The series offers a frequency range of 15 MHz to 2100 MHz and supply voltages of 1.8 V, 2.5 V, and 3.3 V. Output types are CML, HCSL, LVDS, and LVPECL.

Renesas also expanded the original ProXO XF 2.5 x 2.0 mm device to include two new industry-standard 3.2 × 2.5 mm and 5.0 × 3.2 mm plastic packages.

The ProXO+ family can be combined with Renesas’ complementary clock buffers, power, and microcontroller offerings 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 the RZ/G2E processors.

The ProXO+ oscillators are available now. The devices are housed in a 3.2 × 2.5 mm, 8-pin plastic package.
