Product details

MEMS oscillator replaces quartz at 66 MHz

The DSC1101CI2-066.0000 is a MEMS-based XO (Standard) that generates a 66 MHz CMOS output without a quartz crystal — the MEMS resonator is the timing element, which eliminates the crystal's startup reliability and load-capacitance matching concerns.

The Standby (Power Down) function pulls the disable current down to 95 µA max, letting the system cut clock power during sleep modes while the 35 mA max active current supports the 66 MHz CMOS output into a standard load.

6-SMD no-lead footprint

Housed in a 3.20 mm x 2.50 mm 6-SMD no-lead package with a seated height of 0.90 mm, the DSC1101CI2-066.0000 fits tight PCB layouts — the 0.50 mm pitch pads require a standard SMT reflow profile with no via-in-pad needed.

Frequently asked questions

Can the DSC1101CI2-066.0000 replace a standard 66 MHz quartz crystal oscillator?

Yes — it is a drop-in XO replacement that outputs a CMOS clock at 66 MHz. The MEMS resonator eliminates the need for external load capacitors and the quartz crystal's startup matching, so the board layout is simpler and the frequency stability is ±25 ppm over temperature.

What is the standby power-down current of the DSC1101CI2-066.0000?

When the Standby (Power Down) function is active, the supply current drops to 95 µA max. This lets the oscillator be gated off during system sleep without draining the battery.
