The DSC1123DI5-100.0000T is a 100 MHz LVDS-output MEMS oscillator in the DSC1123 series from Microchip Technology, qualified to AEC-Q100 and rated over -40°C to 85°C.
This part carries an AEC-Q100 rating — the OEM auditor will expect PPAP documentation on file.
Package footprint and supply voltage
Housed in a 6-SMD, No Lead package measuring 2.50 mm x 2.00 mm x 0.90 mm — the 0.098" x 0.079" footprint fits the standard MEMS oscillator land pattern for 2.5 x 2.0 mm devices. Supply voltage range is 2.25 V to 3.63 V, covering common 2.5 V and 3.3 V rails without an external LDO. The LVDS output is DC-coupled to the receiver; the common-mode voltage is set by the oscillator, so the receiver input must tolerate 1.2 V typical.
