Product details

20 MHz MEMS XO for industrial clock trees

The DSC1101AI2-020.0000T: Standby (Power Down) function drops supply current to 95 µA max, useful for battery-backed real-time clocks or power-gated sensor nodes where the oscillator must idle without draining the cell.

Housed in a 6-SMD, no-lead exposed pad package measuring 7.00 mm x 5.00 mm with a seated height of 0.90 mm — a standard 7x5 ceramic oscillator footprint shared by many quartz and MEMS XOs. The exposed pad should be connected to a ground plane with a thermal via array to keep the die temperature within the -40 to 85°C operating range under the 35 mA max supply current.

Frequently asked questions

What is the recommended PCB footprint for DSC1101AI2-020.0000T?

The 6-SMD no-lead exposed pad package (7.00 mm x 5.00 mm) follows the standard 7x5 mm ceramic oscillator land pattern. The exposed pad requires a thermal via array to the ground plane for heat dissipation. Consult Microchip's application note for the DSC1101 series for exact pad dimensions.
