Product details

Two fixed clocks for audio/video timing chains

The DSC400-0101Q0083KI1T: This MEMS XO delivers two independent LVCMOS outputs at 45.1584 MHz and 49.152 MHz — the standard sample-rate clocks for professional digital audio, broadcast video, and studio equipment. The ±50 ppm frequency stability holds the timing jitter within the window required for AES3 or SDI serial streams without an external PLL cleanup.

Industrial temperature grade for outdoor or factory-floor deployment

Rated -40°C to 85°C, the DSC400-0101Q0083KI1T keeps the clock edges clean in outdoor telecom cabinets, engine-bay electronics, or factory automation panels where the ambient cycles above 70°C. The MEMS resonator is inherently more vibration-tolerant than a quartz crystal, so the oscillator holds frequency through the shock and vibration of a motor drive or a portable instrument.

New designs can commit to it without a last-time-buy window, and the production line can order against the BOM quantity without obsolescence risk. The 20-VFQFN package with exposed pad requires a thermal via pattern under the centre pad — confirm the footprint matches your reflow profile before committing the board.

Frequently asked questions

What is the frequency of DSC400-0101Q0083KI1T?

The DSC400-0101Q0083KI1T outputs two LVCMOS clocks: 45.1584 MHz on output 1 and 49.152 MHz on output 3. These are standard audio/video sample-rate frequencies.

Is DSC400-0101Q0083KI1T a MEMS oscillator?

Yes, the base resonator is MEMS, not quartz. This gives better vibration and shock resistance compared to a traditional crystal oscillator, and the frequency is factory-programmed — no external load capacitors needed.

What is the difference between DSC400 and DSC600 series?

The DSC400 series is a multi-output MEMS XO with up to four independent frequencies, while the DSC600 is a single-output MEMS oscillator. The DSC400-0101Q0083KI1T specifically provides two fixed outputs; the DSC600 would require two separate parts for the same dual-frequency function.
