Product details

74.25 MHz MEMS XO – obsolete, sourced per RFQ

The DSC1033CE2-074.2500: For existing BOM lines, this part can be sourced through independent distribution channels.

MEMS resonator, CMOS output, 74.25 MHz

This is a MEMS-based oscillator (PureSilicon™ series) delivering a 74.25 MHz CMOS clock with ±25 ppm frequency stability over -20°C to +70°C. The 3.3V supply rail and 4 mA typical supply current make it a low-power fit for video or networking clock trees where 74.25 MHz is a standard pixel clock rate.

4-SMD no-lead – board layout note

Housed in a 3.20 mm x 2.50 mm 4-SMD no-lead package, seated height 0.90 mm.

Frequently asked questions

Is DSC1033CE2-074.2500 obsolete?

Confirming obsolete status avoids ordering a part that may be discontinued, preventing production delays.

What is the replacement for DSC1033CE2-074.2500?

Buyers need a drop-in or functional alternative to keep their design running without re-spin.

Where can I buy DSC1033CE2-074.2500?

Immediate purchase availability is critical for maintenance or small-run production.

What are the specifications of DSC1033CE2-074.2500?

Designers must verify frequency, voltage, and output type to ensure circuit compatibility.

Is DSC1033CE2-074.2500 pin compatible with other oscillators?

Pin compatibility assessment enables quick substitution without PCB layout changes.

What is the lead time for DSC1033CE2-074.2500?

Even for obsolete parts, understanding remaining stock and lead time prevents supply chain gaps.
