Product details

MEMS oscillator with LVDS output at 180 MHz

The LVDS signalling provides low electromagnetic interference and a differential swing that suits point-to-point clock distribution over short PCB traces — common in networking switches, FPGA reference clocks, and automotive Ethernet PHYs.

Supply voltage and current draw

The supply range of 2.25V to 3.63V lets the oscillator run directly from a 2.5V or 3.3V rail without an intermediate regulator.

Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the DSC1123CI5-180.0000T fits the standard 3.2 x 2.5 mm oscillator footprint. The no-lead construction reduces parasitic inductance compared to a gull-wing package, which helps maintain signal integrity at 180 MHz LVDS edge rates.

Frequently asked questions

Does the DSC1123CI5-180.0000T require external load capacitors?

No. As a MEMS oscillator, the DSC1123CI5-180.0000T generates the output frequency internally without a quartz crystal or external load capacitors. The LVDS output is self-contained and drives a 100-ohm differential termination at the receiver.

Can the DSC1123CI5-180.0000T replace a quartz oscillator in an existing design?

The DSC1123CI5-180.0000T is a MEMS-based XO, not a quartz resonator. If the existing design uses a quartz oscillator with the same 3.2 x 2.5 mm footprint, 180 MHz frequency, LVDS output, and 2.25V–3.63V supply, it is a drop-in replacement. MEMS oscillators generally offer better shock and vibration tolerance than quartz, which matters in automotive and industrial environments.
