The DSC1123CI2-125.0000 is a fixed-frequency MEMS-based XO (standard) delivering a 125 MHz LVDS output — a common reference for automotive Ethernet, PCIe Gen 1/2, and high-speed serial links in engine-control or ADAS modules.
Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that matches standard 3.2 x 2.5 mm quartz oscillator pads.
The DSC1123CI2-125.0000 is an active Microchip part (no EOL notice). It is sourced through independent distribution — submit an RFQ with your target quantity and target price, and we will confirm availability and a competitive quote. No stock-holding claim; every order is confirmed at quote time.
Yes — the DSC1123CI2-125.0000 carries an AEC-Q100 rating, meaning it passed the automotive IC qualification suite (temperature cycling, ESD, latch-up, early-life failure).
Functionally yes — it is a drop-in MEMS replacement for a 3.2 x 2.5 mm quartz oscillator with LVDS output. The MEMS resonator is more shock- and vibration-tolerant than quartz, which is an advantage in automotive and industrial environments. The enable/disable function and supply voltage range are standard; confirm the pin 1 logic (enable high) matches your board.
Yes — the LVDS output meets the TIA/EIA-644 standard. It drives a 100 Ω differential termination with a typical swing of 350 mV. Any standard LVDS receiver (FPGA, SerDes, PHY) will interface directly.
