Product details

400 MHz LVPECL MEMS oscillator — active, industrial-rated

The 400 MHz frequency and LVPECL signalling target high-speed clock trees — SERDES reference clocks, FPGA transceiver banks, and 10 GbE PHY timing — where the differential output rejects common-mode noise and the ±10 ppm frequency stability keeps the clock edge within the timing budget across temperature.

6-SMD footprint and supply integration

The 6-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight channel spacing on a high-density PCB.

Frequently asked questions

Is the DSC1122CI5-400.0000T compatible with a 2.5 V supply?

Yes. The supply range is 2.25 V to 3.6 V, so a 2.5 V rail is well within the operating window. No external regulator is needed when moving between 2.5 V and 3.3 V domains.

What does the 'T' suffix mean in DSC1122CI5-400.0000T?

The 'T' suffix designates Tape & Reel packaging, the standard delivery format for automated pick-and-place assembly. The device itself is identical to the non-T variant in electrical and mechanical specifications.
