LVDS signalling at this frequency suits high-speed serial interfaces (Gigabit Ethernet, PCIe reference clocks, SerDes) where low jitter and differential noise immunity are required. ## Automotive-grade qualification and supply flexibility Rated AEC-Q100, this oscillator meets automotive IC qualification standards for temperature, reliability stress, and PPAP — suitable for under-hood or chassis-domain applications that see -20°C to +70°C ambient. ## Package, footprint, and enable/disable control Housed in a 6-SMD no-lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits space-constrained PCBs, though the 6-pin layout requires careful fan-out on two-layer boards.","metaTitle":"DSC1123DE1-131.0720 — Microchip MEMS XO, 131.072 MHz LVDS","metaDescription":"DSC1123DE1-131.0720: Microchip MEMS oscillator, 131.072 MHz LVDS output, AEC-Q100, 2.25-3.63 V supply.

The MEMS resonator offers faster startup and better shock/vibration tolerance, but the pinout and footprint (6-SMD) must match the quartz oscillator's layout. Verify the Enable/Disable logic polarity and supply voltage range (2.25 V to 3.63 V) against your existing design before swapping."},{"question":"Does the DSC1123DE1-131.0720 have a datasheet?","answer":"Yes, a full datasheet is available from Microchip. The spec table on this page carries the key ratings: 131.072 MHz LVDS output, ±50 ppm stability, 2.25 V to 3.63 V supply, 32 mA max supply current, and AEC-Q100 qualification.
