Product details

337.6 MHz LVDS clock for SERDES and FPGA reference

The DSC1103CI5-337.6000 is a MEMS-based XO (Standard) oscillator delivering a 337.6 MHz LVDS output — a frequency commonly used as a reference clock for high-speed SERDES transceivers, FPGA gigabit transceivers, and Ethernet PHYs that require a clean differential clock above 300 MHz.

MEMS reliability and package footprint

Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint is compatible with standard 6-pin oscillator land patterns; the 0.50 mm pad pitch requires careful fan-out on two-layer boards.

Active production — no end-of-life watch

No NRND or EOL notice has been issued for this order code.

Frequently asked questions

Can DSC1103CI5-337.6000 be used as a replacement for a quartz oscillator?

Yes, if the board is designed for a standard 6-pin LVDS oscillator footprint. The MEMS resonator gives better vibration immunity than quartz and the ±10 ppm stability matches many quartz XO specifications. Confirm the supply voltage (2.25 V to 3.63 V) and output type (LVDS) match the original quartz part.
