Product details

250 MHz LVDS clock with AEC-Q100 qualification

The DSC1123AI2-250.0000T is an active-production MEMS-based XO (Standard) oscillator delivering a 250 MHz LVDS output clock. The AEC-Q100 rating confirms the part has passed the automotive-grade stress tests — temperature cycling, ESD, and latch-up — making it suitable for under-hood and chassis-domain modules where a quartz crystal might crack under vibration.

Supply tolerance and power budget

The wide supply range from 2.25 V to 3.63 V covers both 2.5 V and 3.3 V rails without an external regulator — a BOM simplification in mixed-voltage designs. Maximum supply current is 32 mA when enabled, and 22 mA in disabled mode via the Enable/Disable function, which allows the clock tree to be gated for power savings during system sleep.

Package, footprint, and temperature range

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

No direct pin-compatible second source is listed, but the DSC1123 series family offers other frequencies and stability grades for cross-referencing within the same footprint.

Frequently asked questions

Is the DSC1123AI2-250.0000T AEC-Q100 qualified?

Yes. The DSC1123AI2-250.0000T carries an AEC-Q100 rating, meaning it has passed automotive-grade qualification for temperature, reliability, and ESD stress. This qualifies it for use in under-hood and cabin electronic modules where commercial-grade oscillators would not be accepted.

Can the DSC1123AI2-250.0000T replace a quartz oscillator in my design?

Yes, if the board layout accepts the 7.00 mm x 5.00 mm 6-SMD package. The MEMS resonator offers improved shock and vibration tolerance compared to quartz, and the ±25 ppm frequency stability meets typical Ethernet and CAN-FD clocking budgets. For jitter-critical applications above 1 Gbps, verify the phase-noise performance against your SerDes requirements.
