The DSC1001DE1-090.0000T is a 90 MHz MEMS-based XO (Standard) from Microchip's DSC1001 family, delivering a CMOS output with ±50 ppm frequency stability across its -20°C to 70°C operating range. The supply voltage range of 1.8V–3.3V lets it run directly off a 1.8V FPGA bank or a 3.3V microcontroller rail without a level translator or secondary LDO.
Product status is Active — no EOL notice, no NRND flag. The 2.50mm x 2.00mm footprint fits tight clock-tree layouts on multi-layer boards.
Active supply current is 8.7 mA max at 90 MHz — low enough for a shared 3.3V rail with other peripherals, but budget the 8.7 mA into the rail's total load if the oscillator is the only clock on that supply.
