The DSC1001BE5-020.0000 is a 20 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±10 ppm frequency stability across its -20°C to 70°C operating range.
Supply voltage and power-down mode
Operates from a single 1.8V to 3.3V supply, drawing a maximum of 6.5 mA — the wide input range lets it share a rail with the core or I/O bank of a 3.3V or 1.8V MCU without a level translator.
Package and footprint for automotive PCB layout
Housed in a 4-SMD, no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm — the standard 5×3.2 mm oscillator footprint fits most automotive ECU layouts without a board spin. Surface-mount assembly; the no-lead design reduces parasitic inductance compared to a through-hole crystal, keeping the clock edge clean for high-speed digital interfaces.
