MEMS oscillator for precision clocking at 22.5792 MHz
The DSC1121AL5-022.5792 is a MEMS-based standard oscillator (XO) producing a 22.5792 MHz CMOS output — a frequency commonly used in audio DAC reference clocks and video timing chains.
Supply range and output control
The supply voltage accepts 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external regulator. Maximum supply current is 22 mA at full load, so the oscillator's draw is modest even in multi-clock designs. The 6-SMD no-lead package (7.00 mm × 5.00 mm, 0.90 mm seated height) is a standard footprint for industrial oscillators, easily routed on two-layer PCBs.
