20 MHz MEMS oscillator with military temperature range
The DSC1101DM5-020.0000 is a 20 MHz XO (Standard) oscillator built on a MEMS resonator, delivering a CMOS output across a 2.25V to 3.6V supply range. Frequency stability is ±10 ppm, tight enough to clock a UART at 115200 baud or an MCU PLL without additional trimming.
Microchip lists the DSC1101DM5-020.0000 as Obsolete. Available through independent surplus distribution — quantities are lot-specific and confirmed at RFQ.
Standby function and supply current
A Standby (Power Down) pin disables the output and drops supply current to 95 µA max, useful for battery-powered systems that need to gate the clock tree without a separate load switch. Active supply current is 35 mA max at 20 MHz — typical for a MEMS oscillator at this frequency; the CMOS output swings rail-to-rail and drives standard logic inputs directly.
6-VDFN package and board layout
Housed in a 6-VDFN measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the package suits space-constrained PCBs. The 0.50 mm pitch pads require careful solder-paste stencil design to avoid bridging.
