Product details

159.375 MHz LVPECL clock source with MEMS resonator

The DSC1122AI1-159.3750T is a Microchip DSC1122 series XO (Standard) delivering a 159.375 MHz LVPECL output from a MEMS resonator, housed in a 6-SMD no-lead exposed pad package measuring 7.00mm x 5.00mm. LVPECL output at this frequency suits high-speed serial links (Gigabit Ethernet, Fibre Channel, SONET) where the differential signal maintains noise margin over PCB traces.

Industrial temperature grade and wide supply tolerance

Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without an extra LDO — the internal regulator rejects supply ripple down to the PSRR of the MEMS PLL.
