Product details

233.3333 MHz LVDS clock with ±10 ppm hold

The DSC1103CI5-233.3333: A MEMS-based XO (Standard) delivering 233.3333 MHz on an LVDS output — the ±10 ppm frequency stability means the clock edge jitter stays within the timing budget for a 10 GbE SERDES reference or a high-speed ADC sample clock without an external PLL cleanup.

Standby power-down drops to 95 µA

Industrial temp grade and 6-SMD footprint

Housed in a 3.20 mm x 2.50 mm 6-SMD no-lead package (0.90 mm seated height) — the small footprint and low profile suit dense PCB layouts, but the no-lead land pattern requires a solder-paste stencil aperture matched to the pad geometry for reliable fillet formation.

Frequently asked questions

Where can I buy DSC1103CI5-233.3333?

No stock-holding claim is made; submit an RFQ for a firm quote.

What is the standby function of DSC1103CI5-233.3333?

The Standby (Power Down) function disables the LVDS output and reduces supply current to 95 µA max. The oscillator stops and the output goes high-impedance; re-enabling standby restarts the clock after the oscillator settle time.

What is the frequency stability of DSC1103CI5-233.3333?

This is tight enough for most Ethernet and serial-link reference clocks without external trimming.

Can DSC1103CI5-233.3333 operate at a 2.5 V supply?

Yes, the supply voltage range is 2.25 V to 3.63 V, so a nominal 2.5 V rail is within spec. The LVDS output common-mode voltage and swing are referenced to the supply, so the receiver input threshold must be compatible with the resulting levels.

Is DSC1103CI5-233.3333 RoHS compliant?

The evidence does not list a separate RoHS compliance code, but the DSC1103 series is typically RoHS-compliant per Microchip's standard material declaration. Confirm the specific date code and certificate at RFQ.
