IQD wideband clock meets 100G Ethernet jitter spec

A range of low jitter clock oscillators from IQD cover a frequency range from 1MHz up to 1.5GHz and can be used for high speed serial interfaces such as Ethernet and PCI Express.

The devices, IQXO-940, IQXO-942 and IQXO-944, have a specified phase jitter performance down to between 0.9ps and 0.05ps rms max depending upon the selected frequency and specification.

The oscillators are available in a choice of two ceramic 6-pad hermetically sealed packages 7.0 x 5.0mm and 5.0 x 3.2mm with different height options down to 1.5mm.

Designed primarily for applications such as Ethernet (10G/40G/100G), DSL/ASDL, PCI Express, Serial Rapid I/O (SIRO), Wi-Fi, and WiMAX/W-LAN, three output options can be specified, CMOS, LVPECL and LVDS.

The new IQD oscillators can operate at either 2.5V or 3.3V and if required an enable or disable output can be specified. Operating over the industrial temperature range of -40 to 85 degrees C, all inclusive frequency stabilities down to ±10ppm over a period of 10 years can be specified.
