155.52 MHz LVPECL clock for high-speed signal chains
This DSC1122CL2-155.5200T delivers a 155.52 MHz LVPECL output from a MEMS resonator — a frequency commonly found in 10 Gigabit Ethernet, Fibre Channel, and SONET/SDH line cards where the differential swing and fast edge rate of LVPECL drive long PCB traces with controlled impedance.
Wide supply tolerance simplifies rail selection
The 6-SMD no-lead package (3.20 mm × 2.50 mm footprint, 0.90 mm seated height) is a standard MEMS oscillator land pattern shared across the DSC1122 family, so a layout designed for this part can also accept other frequencies in the same series.
