The DSC1505AI3A-100M0000T is a 100 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC150X series, delivering an LVCMOS output from a 1.8V supply rail.
The 1.8V supply matches the core voltage of many modern FPGAs, SoCs, and low-power ASICs — no extra level shifter needed between the oscillator output and the clock input. Maximum supply current is 7.5 mA, and standby (power-down) mode drops draw to 1 µA typical — a meaningful saving in battery-powered or duty-cycled designs.
Housed in a 4-VDFN with exposed pad, 7.00 mm × 5.00 mm body, 0.90 mm seated height — the exposed pad needs a thermal via under the package to the ground plane for best heat transfer and EMI containment.
