Product details

Quad-output MEMS oscillator for multi-clock BOM consolidation

The output frequencies cover 148.35MHz/148.5MHz on output 1, 156.25MHz on output 2, 208.333333MHz on output 3, and 197.8MHz/198MHz on output 4 — a set that directly addresses video timing (148.5 MHz for 1080p/4K), Ethernet reference (156.25 MHz for 10GbE), and high-speed FPGA transceiver clocks (208.333333 MHz).

Supply voltage flexibility and temperature range

Operating from a 2.25V to 3.6V supply rail, this oscillator accepts common 2.5V or 3.3V logic rails without an external regulator — the internal LDO cleans the supply noise for the MEMS resonator.

The 20-VFQFN exposed-pad package measures 5.00mm x 3.20mm with a 0.90mm seated height.

Frequently asked questions

What is the exact output frequency of DSC400-3333Q0099KI2T?

Design engineers need to confirm the oscillator matches the required clock frequency (148.35 MHz and 148.5 MHz) for their application.

Where can I buy DSC400-3333Q0099KI2T with stock?

Sourcing buyers need immediate availability to avoid production delays; knowing the distributor with stock is critical for BOM fulfillment.

What is the price of DSC400-3333Q0099KI2T per unit?

Procurement requires pricing to compare with budget and alternative parts; price drives sourcing decisions.

What is the package and footprint of DSC400-3333Q0099KI2T?

Design and layout engineers need physical dimensions (5.00mm x 3.20mm, 20-VFQFN) to ensure PCB fit and soldering compatibility.

Is DSC400-3333Q0099KI2T still active or obsolete?

Brokers and buyers need lifecycle assurance; an active status avoids supply chain disruption and last-time buy scrambles.

What is a cross-reference or alternative for DSC400-3333Q0099KI2T?

When stock is low or lead times long, engineers and buyers need a direct equivalent (same frequency, output, package) to keep designs viable.
