Product details

333.3333 MHz LVDS clock for high-speed signal chains

Rated over -40°C to 125°C with ±20 ppm stability, it holds timing margin in outdoor telecom cabinets, engine-bay electronics, and industrial motor drives where quartz oscillators may drift off frequency.

Active production — sourced per BOM quantity

The MEMS resonator construction avoids the long lead times sometimes seen with quartz crystals; typical sourcing lead is confirmed at RFQ.

6-VDFN package and board integration

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits dense PCB layouts near the processor or transceiver.

Frequently asked questions
