The DSC1123AI2-125.0000T is a 125 MHz LVDS MEMS oscillator from Microchip's DSC1123 family, qualified to AEC-Q100. The LVDS output delivers low-jitter differential signalling for high-speed SERDES, Ethernet PHY reference clocks, and FPGA/SoC clock inputs — the 125 MHz frequency is a common multiple for 10/100/1000BASE-T and PCIe Gen1 reference rates.
Supply range and enable/disable control
The device operates from 2.25 V to 3.63 V, covering 2.5 V and 3.3 V logic rails without an external regulator.
Package and board-level integration
Housed in a 6-SMD no-lead exposed-pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm.
