Product details

LVPECL output at 100 MHz — clock tree fit

The DSC1122CI2-100.0000T: This oscillator outputs a 100 MHz LVPECL signal, the standard reference clock for gigabit Ethernet PHYs, FPGA transceivers, and SERDES PLLs.

MEMS resonator — reliability and supply independence

Product status is Active, meaning Microchip continues to manufacture and support this part.

Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm, with a seated height of 0.90 mm. Surface-mount reflow follows standard lead-free profiles.

Frequently asked questions

Does DSC1122CI2-100.0000T support a 3.3 V supply?

Yes. The LVPECL output swing is referenced to the supply voltage.

What is the output type of DSC1122CI2-100.0000T?

LVPECL. This differential output is the standard for high-speed clock distribution in SERDES, FPGA transceivers, and 10/100/1000 Ethernet PHYs. The pair must be AC-coupled or DC-terminated per the receiver's common-mode range.
