Product details

The DSC1001DI5-066.4860T is a MEMS-based XO (Standard) oscillator from Microchip Technology, delivering a 66.486 MHz CMOS output with ±10 ppm frequency stability across -40°C to 85°C.

Supply voltage and current budget

Operating from a 1.8V to 3.3V supply rail, the oscillator draws 7.2 mA max during active operation — a low enough figure to fit into a 50 mA power budget for a small automotive ECU or sensor module.

Housed in a 4-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits into compact PCB layouts typical of automotive modules and portable equipment. Surface-mount assembly with a standard reflow profile; no special pad geometry required beyond the 4-pin footprint. Check the MSL before placing — MEMS oscillators are typically MSL 1, but confirm on the reel label.

Frequently asked questions

Where can I buy DSC1001DI5-066.4860T with stock?

No stock-holding claim is made here.

Is DSC1001DI5-066.4860T suitable for automotive applications?

Yes. It carries an AEC-Q100 rating, which qualifies it for automotive-grade reliability stress and temperature cycling.

How does the standby function work on DSC1001DI5-066.4860T?

The standby (power-down) function disables the output and reduces supply current to 15 µA max. It is controlled by a dedicated pin — pulling it low (or high, depending on the logic) puts the oscillator into standby. This allows system-level power gating without an external switch.

Can I replace a quartz oscillator with DSC1001DI5-066.4860T?

Yes, if the board accepts a 4-SMD no-lead package and 1.8V to 3.3V supply. The MEMS construction provides better shock and vibration tolerance than quartz, and the ±10 ppm stability is comparable to a standard quartz XO. Verify the footprint and supply voltage compatibility first.
