The LVDS output delivers a differential signal with typical 350 mV swing into 100 Ω, keeping jitter low for the 27 MHz reference needed by video encoders, Ethernet PHYs, or FPGA clock inputs.
Microchip lists the DSC1123CL2-027.0000 as Active — it is in production and open for new designs. The 6-SMD no-lead package (3.20 mm × 2.50 mm footprint) is a standard MEMS oscillator land pattern shared across the DSC1123 family.
Yes, if the board expects an LVDS differential clock at 27 MHz. The MEMS oscillator is pin-compatible with many 6-pin 3.2×2.5 mm quartz oscillators, but the supply voltage must be within 2.25 V to 3.63 V and the enable/disable logic levels must match. No external load capacitors are needed, so the board layout is simpler than a quartz crystal circuit.
