Product details

MEMS oscillator for video timing and automotive use

The DSC1001DI2-074.1758T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 74.1758 MHz CMOS output — the exact pixel clock frequency for 59.94 Hz video formats used in broadcast and professional video equipment.

Frequency stability and supply voltage flexibility

The supply voltage range of 1.8V to 3.3V means the same BOM line works across 1.8V-core SoCs, 2.5V FPGA banks, and 3.3V peripheral logic — no separate regulator or level shifter needed for the oscillator rail.

Standby mode for power-sensitive designs

Housed in a 4-SMD, no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — the same footprint as many quartz crystal oscillators, so a drop-in replacement is possible if the pad layout matches.

Frequently asked questions

Where can I buy DSC1001DI2-074.1758T?

We source this active Microchip oscillator through independent distribution. Submit an RFQ with your target quantity and lead-time window — we confirm availability and price per your BOM line.

Is DSC1001DI2-074.1758T AEC-Q100 qualified?

Yes — the ratings include AEC-Q100, meaning it has passed automotive-grade reliability stress tests and is suitable for under-hood or cabin electronics in vehicles.

Can DSC1001DI2-074.1758T replace a quartz crystal oscillator?

The MEMS base resonator offers better shock and vibration tolerance than a quartz crystal, and the ±25 ppm stability is comparable. If your board layout matches the 2.5×2.0 mm 4-SMD footprint, it can drop in without a PCB change.

What is the output type of DSC1001DI2-074.1758T?

CMOS output — it drives standard logic-level clock inputs directly. No external termination or level translation is needed for 1.8V, 2.5V, or 3.3V rails.
