Product details

MEMS timing for 1.8V rails

Runs on a 1.8V supply rail, drawing 7.5 mA max while oscillating, and drops to 1 µA typ in standby (power-down) mode — the standby pin pulls the output to high-impedance and halts the MEMS drive, so a battery-powered design can gate the clock without a separate load switch.

Housed in a 4-VDFN with exposed pad — 7.00 mm x 5.00 mm body, 0.90 mm seated height. The exposed paddle on the bottom is the thermal path; the datasheet layout shows a via-stitched ground pad under the part to pull heat into the PCB plane. Surface-mount only — no through-hole variant. The VDFN package reflows with a standard lead-free profile; the exposed pad wets well if the solder paste aperture covers at least 50% of the pad area.

Frequently asked questions

Is DSC1505AI3A-8M000000 a direct replacement for a quartz oscillator?

Yes — it is a drop-in functional replacement for a standard 8 MHz quartz XO with LVCMOS output, same supply voltage, same footprint. The MEMS base resonator eliminates the quartz cold-start delay and is more resistant to vibration and shock. No external load capacitors are needed.

How do I use the standby (power-down) function on DSC1505AI3A-8M000000?

The standby pin (typically pin 1 on the 4-VDFN) is active-low — pulling it to GND puts the oscillator into power-down mode, drawing 1 µA typ and disabling the output. Releasing the pin or driving it high restarts the MEMS drive and output within a few milliseconds. No external pull-up is needed if the driving logic has a push-pull output.

Is DSC1505AI3A-8M000000 compatible with 1.8V systems?

Yes — the supply voltage is 1.8V, and the LVCMOS output swings rail-to-rail, so it drives 1.8V logic inputs directly without a level shifter. The input threshold is compatible with 1.8V CMOS levels.
