Product details

Dual-frequency LVDS clock for video timing chains

The DSC400-3333Q0089KI1T delivers two LVDS clock outputs at 148.35 MHz and 148.5 MHz — the standard pixel clock rates for 1080p/60 Hz video and broadcast reference. A single oscillator replaces two quartz cans, saving board area and reducing BOM count.

Supply flexibility and temperature range for industrial use

The 2.25V to 3.6V supply range lets this oscillator run from a 2.5V or 3.3V rail without a separate LDO — one less part to qualify.

Microchip Technology is the sole manufacturer; no second-source pin-compatible drop-in is listed on the public record.

Frequently asked questions

Is DSC400-3333Q0089KI1T compatible with 3.3V LVDS?

Yes. The supply voltage range is 2.25V to 3.6V, so a 3.3V rail is within spec. The LVDS output is a differential pair — the receiver must be LVDS-compatible; it is not a single-ended CMOS output.

Can I use DSC400-3333Q0089KI1T as a replacement for a standard quartz oscillator?

If your board expects a single-ended CMOS clock, no — this part outputs LVDS, a differential signal that requires a 100-ohm termination at the receiver. If your design already uses an LVDS input, the MEMS-based DSC400 is a drop-in replacement for a quartz LVDS oscillator with better shock tolerance.
