Product details

100 MHz LVDS clock source — MEMS, not quartz

The DSC1103AE1-100.0000T is a 100 MHz LVDS oscillator built on a MEMS resonator rather than a quartz crystal. It delivers a ±50 ppm frequency stability across its -20°C to 70°C operating range, which is the standard tolerance for 1000BASE-T Ethernet, PCIe reference clocks, and FPGA transceiver lanes — the LVDS output keeps jitter low over a twisted-pair or differential trace.

Runs from 2.25 V to 3.63 V, covering both 2.5 V and 3.3 V rails without a separate LDO.

Housed in a 6-SMD, no-lead package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm.

Listed as Active by Microchip Technology with no announced end-of-life.

Frequently asked questions

Can DSC1103AE1-100.0000T replace a quartz oscillator?

Yes, if the board is laid out for a 6-SMD, no-lead footprint (7.0 × 5.0 mm) and expects an LVDS input. The MEMS resonator is a drop-in replacement for a quartz XO of the same package and output type — no external load capacitors or feedback resistors are needed. The ±50 ppm stability matches most quartz oscillators in this frequency range.

What is the frequency stability of DSC1103AE1-100.0000T?

±50 ppm over the -20°C to 70°C operating range. That is the total frequency deviation including temperature, supply voltage, and aging — typical for a 100 MHz reference in networking or FPGA applications.

What voltage does DSC1103AE1-100.0000T require?

It accepts 2.25 V to 3.63 V, so it works on both 2.5 V and 3.3 V rails. No external regulator is needed if your rail is within that window.
