Active MEMS oscillator at 48 MHz – LVCMOS, 1.8V, standby
The DSC1505AI3A-48M00000 is a Microchip MEMS-based XO (Standard) that outputs 48 MHz LVCMOS from a 1.8 V supply rail, drawing 7.5 mA max in active operation.
Standby (power down) mode – 1 µA typical disable current
The standby (power down) function, enabled through the device's control pin, drops the supply current to 1 µA typical (max value not specified) — this lets the oscillator be gated off during system sleep without a separate load switch.
Active lifecycle – no obsolescence pressure
It is suitable for both new designs and ongoing production replenishment. Sourced through independent distribution; quoted to order against the BOM quantity.
Package and footprint – 4-VDFN exposed pad, 7.00 mm x 5.00 mm
Housed in a 4-VDFN exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm max. The exposed pad provides a low thermal resistance path to the PCB ground plane; the datasheet layout recommendation should be followed for optimal thermal and mechanical performance.
