Product details

Dual-frequency MEMS XO — what the ratings mean for the BOM line

The DSC6122CI2A-00B3: Maximum current draw is 3 mA typical — low enough that a shared 100 mA LDO can power several of these oscillators plus the downstream load without exceeding the regulator's dropout headroom.

Lifecycle reality — obsolete, sourced through independent channels

Microchip lists the DSC6122CI2A-00B3 as Obsolete. No official successor order code is recorded, so a drop-in replacement from the same manufacturer is not available.

Frequently asked questions

What are the output frequencies and stability of the DSC6122CI2A-00B3?

It outputs two CMOS frequencies: 6.1298 MHz and 6.1679 MHz. The MEMS resonator keeps the stability consistent without the aging drift typical of quartz-based oscillators.

What supply voltage does the DSC6122CI2A-00B3 require?

Maximum current draw is 3 mA typical, so it can share a low-current LDO with other low-power devices on the same rail.

Where can I buy the DSC6122CI2A-00B3?

No stock-holding claim — each RFQ is handled individually.
