The DSC1101DI5-018.4320T delivers an 18.432 MHz CMOS output from a MEMS resonator, specified to ±10 ppm absolute pull range (APR). This APR figure is the total frequency deviation over the full operating envelope — supply voltage, temperature, and aging — so the system clock jitter budget starts from this ±10 ppm ceiling.
Microchip lists the DSC1101DI5-018.4320T as Active. The 6-VDFN package (2.50 mm × 2.00 mm footprint, 0.90 mm seated height) suits space-constrained PCBs in industrial and telecom applications where the -40 to +85°C temperature grade is required.
Standby power-down and CMOS drive
With the standby function asserted, the oscillator draws 95 µA max — the MEMS resonator stops and the output goes high-impedance. The 35 mA max active current at 18.432 MHz is typical for a CMOS-output XO at this frequency; the CMOS rail-to-rail swing eliminates the need for a termination resistor on short traces.
