Product details

90 MHz MEMS oscillator — DSC1121AI1-090.0000

Supply rail and temperature — fit for industrial boards

Absolute pull range is ±50 ppm — the frequency accuracy over temperature and aging is tight enough for a 100BASE-TX clock or a general-purpose processor reference.

Package and board layout — 6-VDFN exposed pad

Housed in a 7.00 mm x 5.00 mm, 6-VDFN package with an exposed pad. The 0.90 mm seated height keeps it low-profile. Surface-mount, supplied in tube.

Sourcing and lifecycle — active production

Active product status per Microchip Technology — no NRND or EOL notice on file.
