Product details

156.25 MHz MEMS clock – AEC-Q100 grade on a 7.0×5.0 mm footprint

The DSC1121AE2-156.2500 is a 156.25 MHz MEMS-based oscillator with CMOS output, ±25 ppm frequency stability, and a 2.25V–3.6V supply range. Rated AEC-Q100, the part is suited for automotive environments where the OEM auditor expects PPAP documentation — not just a datasheet claim of 'automotive-capable'. The 6-SMD no-lead exposed-pad package (0.276" × 0.197") keeps a low 0.90 mm seated height, fitting tight board stacks in engine-control or ADAS sensor modules.

Supply and output – 2.25V–3.6V rail, CMOS, enable/disable

The 2.25V–3.6V supply range covers 2.5V and 3.3V rails without a separate LDO — a single supply rail serves both the oscillator and the downstream logic.
