Ultra-low-jitter clock oscillators optimized for optical DSPs

This post was originally published on this site

Raltron Electronics Inc. has introduced a new series of ultra-low-jitter clock oscillators, targeting high frequency digital signal processors (DSPs) in optical applications. These new oscillators address the demand for lower jitter clocks to reduce noise in systems as network bandwidths increase with faster data rates.

The CL2520 series of LVDS clock oscillators is designed to support optical modules commonly used in networking and data center applications. These include quad small form-factor pluggable (QSFP), octal small form-factor pluggable (OSFP), and C form-factor pluggable 2 (CFP2) optical transceivers, as well as Ethernet, metro, and long-haul.

The CL2520 Series, housed in a 2.5 × 2.0 mm package, offers a jitter performance of 80 fs typical at 156.25 MHz, with power supply options of 1.8 V, 2.5 V, and 3.3 V. The clock oscillators also are available in a continuous power supply version from 2.5 V to 3.3 V. The frequency range covers 6.000 MHz to 175.000 MHz.

Most frequencies of the CL25250 series are available with a six to eight week lead time. However, select frequencies are in stock at key Raltron distributors.
