The 6-VDFN package (5.00 mm x 3.20 mm, 0.90 mm seated height) is a standard footprint that routes easily on a two-layer board.
For a battery-backed RTC or a sensor node that sleeps most of the time, the oscillator's own draw during standby is negligible — the 35 mA active max is only present when the clock is actually running.
18.432 MHz, CMOS output, ±10 ppm stability over -40°C to 105°C.
Yes — the standby (power-down) function disables the output and drops supply current to 95 µA max.
It is a MEMS-based XO with CMOS output — it drops directly into a clock input expecting a CMOS-level square wave from a crystal oscillator module. Confirm the footprint (6-VDFN) and supply voltage range match the existing PCB layout.
The DSC1121 series offers lower jitter and a wider frequency range, but the DSC1101 series covers the common 1 MHz to 150 MHz band with ±10 ppm or ±25 ppm stability options. For 18.432 MHz at ±10 ppm, the DSC1101BL5-018.4320 is the direct fit.
