156.25 MHz LVPECL clock source
The DSC1122BE2-156.2500T is a standard MEMS oscillator (XO) delivering a 156.25 MHz LVPECL output — a common reference frequency for 10 Gigabit Ethernet, Fibre Channel, and FPGA transceiver banks that expect a differential clock.
Supply range and enable/disable
Operates from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator. When enabled, the device draws 58 mA max — typical for a 156.25 MHz LVPECL driver driving a 50-ohm terminated line.
Housed in a 6-SMD no-lead package measuring 5.0 mm x 3.2 mm with a seated height of 0.9 mm — a compact footprint that fits tight board layouts without requiring via-in-pad. It suits indoor networking gear, test equipment, and office electronics, but not automotive or outdoor enclosures where ambient exceeds 70°C.
