Product details

Quad-output MEMS oscillator for multi-clock BOM consolidation

It delivers four independent output frequencies: 148.35 MHz and 148.5 MHz on output 1, 156.25 MHz on output 2, 25 MHz on output 3, and 197.8 MHz with 198 MHz on output 4. Each output can be configured as LVCMOS or LVDS, giving the designer flexibility to drive both single-ended and differential clock domains from one device. The Enable/Disable function allows unused outputs to be gated off for power savings during idle modes.

Frequency stability is ±25 ppm across the full temperature range, which keeps the clock edge jitter within the timing budget for 148.5 MHz video links and 156.25 MHz Ethernet reference clocks.

Package, supply voltage, and PCB layout notes

Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the device requires a thermal via array under the pad for proper heat dissipation and electrical grounding. The supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails without an external regulator.

Active production, no last-time-buy concern

The product status is Active.

Frequently asked questions

What frequencies does the DSC400-3133Q0100KI2 output on each channel?

Output 1: 148.35 MHz and 148.5 MHz (dual frequency). Output 2: 156.25 MHz. Output 3: 25 MHz. Output 4: 197.8 MHz and 198 MHz (dual frequency). All outputs are available as LVCMOS or LVDS.

Does the DSC400-3133Q0100KI2 require an external crystal?

No. The DSC400 uses a MEMS resonator integrated inside the package. No external crystal or quartz is needed — just a clean supply voltage between 2.25 V and 3.6 V.
