The DSC1001AE2-080.0000 is an 80 MHz MEMS-based XO from Microchip's DSC1001 series, delivering a CMOS output with ±25 ppm frequency stability across its -20°C to +70°C operating range. Rated for a supply voltage of 1.8V to 3.3V, it draws a maximum of 10.5 mA — the wide input range lets it run directly from a 1.8V core rail or a 3.3V I/O bank without an intermediate LDO.
Standby function and package footprint
Housed in a 4-SMD, No Lead Exposed Pad package (7.00 mm x 5.00 mm, 0.90 mm seated height), the exposed pad provides a low-thermal-resistance path to the PCB ground plane, helping keep the MEMS resonator stable under temperature gradients. Surface-mount assembly with the standard 4-pin footprint — the pad layout matches the common 7x5 mm oscillator land pattern, so no board spin is needed if you're migrating from a quartz-based XO in the same form factor.
