Product details

200 MHz LVPECL MEMS oscillator — what it buys the design

The LVPECL output delivers the low-jitter, differential clock that high-speed SERDES, FPGAs, and 10G Ethernet PHYs require — the 200 MHz frequency is a common reference for 10GBASE-R and PCIe Gen3/Gen4 clocking.

Supply voltage range and temperature grade

Supply voltage spans 2.25 V to 3.6 V, covering the common 2.5 V and 3.3 V rails used in high-speed digital systems.

Package, footprint, and enable/disable function

Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight board layouts.

Frequently asked questions

Can DSC1122CI2-200.0000T replace a standard quartz oscillator at 200 MHz?

Functionally yes, but the pinout and output type must match. This is a MEMS oscillator with LVPECL output — a standard quartz oscillator at 200 MHz may have a different output (LVDS, HCSL, or CMOS) and a different package footprint. The DSC1122CI2-200.0000T uses a 6-SMD 3.2x2.5mm no-lead package; confirm your PCB footprint and signal termination before substituting.
