Product details

100 MHz LVDS MEMS oscillator – active production

The LVDS output pairs with high-speed digital loads — FPGA reference clocks, SERDES, or Ethernet PHY — where the differential swing rejects common-mode noise on the clock trace. Supply voltage spans 2.25V to 3.63V, so a single BOM line covers 2.5V and 3.3V clock domains without a separate regulator. The 6-SMD no-lead package measures 5.0 mm × 3.2 mm with a seated height of 0.9 mm max — standard footprint that places without tombstoning risk on a typical reflow profile. Check the MSL before you place it; MEMS oscillators generally ship MSL 1, but the reel label is the final word.

Frequently asked questions

Is DSC1103BI1-100.0000 RoHS compliant?

The evidence does not explicitly list RoHS compliance, but Microchip's DSC1103 series is typically RoHS-compliant and lead-free. Confirm the specific date/lot code on the reel label for your jurisdiction.

Is DSC1103BI1-100.0000 compatible with 3.3V?

Yes. The supply voltage range is 2.25V to 3.63V, so a 3.3V rail is within spec. The LVDS output swing scales with Vdd, but the receiver threshold is set by the LVDS standard, not the supply — no level translation needed.

Can I replace a standard crystal oscillator with the DSC1103BI1?

Functionally yes — the DSC1103BI1 is a drop-in XO replacement in the same 5.0 mm × 3.2 mm 6-SMD footprint. The key difference is the MEMS resonator vs quartz: MEMS offers better shock/vibration tolerance and faster start-up, but the output is LVDS, not CMOS/LVTTL. Your load must accept a differential clock.

What is the closest pin-compatible alternative to DSC1103BI1-100.0000?

Within Microchip's DSC1103 series, any 100 MHz LVDS variant with the same 6-SMD package and supply range is pin-compatible. The SiT9102 series from SiTime offers a similar MEMS LVDS XO in the same footprint, but the supply range and standby function may differ — verify the pinout before substitution.
