The DSC1123AI5-322.2656T is a MEMS-based XO delivering a 322.2656 MHz LVDS output — a clean reference clock for 10GbE, Fibre Channel, or FPGA transceiver banks that require a low-jitter differential signal. Supply voltage spans 2.25V to 3.63V — it runs from a 2.5V or 3.3V rail without an external LDO, and the Enable/Disable function lets the system shut the oscillator down to 22 mA max draw when the link is idle.
Package and footprint — 6-SMD with exposed pad
The package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard 7x5 oscillator footprint that matches many crystal-oscillator land patterns.
