Product details

200 MHz LVDS clock source with AEC-Q100 qualification

The LVDS signalling keeps jitter low over the 0.50 mm pitch traces typical of a 6-layer automotive ECU board.

Supply rail flexibility and disable function

The 2.25 V to 3.63 V supply range lets the oscillator run from a 2.5 V FPGA bank or a 3.3 V MCU rail without a dedicated LDO. At 32 mA max supply current, the thermal load on the 7.0 mm × 5.0 mm exposed-pad package is low even in a sealed enclosure.

Microchip lists the DSC1123AE1-200.0000T as Active.

Frequently asked questions

Can the DSC1123AE1-200.0000T replace a standard 200 MHz crystal oscillator?

This is a MEMS-based XO, not a bare crystal. It includes the oscillator circuit and outputs a clean LVDS clock — no external load capacitors or inverter stage needed. It directly replaces a 200 MHz LVDS oscillator in the same 6-SMD footprint, but not a quartz crystal resonator.

What does the AEC-Q100 rating mean for this oscillator?

AEC-Q100 Grade 1 or Grade 2 qualification (the exact grade is not specified in the datasheet excerpt) ensures the part has passed accelerated reliability tests including temperature cycling, ESD, and latch-up. It is suitable for automotive ECU, ADAS camera, or telematics applications that require the same qualification as the main processor.

Does the DSC1123AE1-200.0000T have an enable/disable function?

Yes. The Enable/Disable function allows the output to be gated. When disabled, the supply current drops to 22 mA max, versus 32 mA max when enabled.
