This frequency aligns with SONET/SDH data rates (OC-3/STM-1) and is common in telecom line cards, base stations, and high-speed networking gear where differential signaling keeps jitter under control. ## AEC-Q100 qualification and industrial temperature range Rated AEC-Q100, the part carries automotive-grade reliability testing — temperature cycling, ESD, and latch-up — so it suits under-hood or cabin electronics that see -40 to 85°C ambient. The ±10 ppm frequency stability holds across that band, which means a GPS module or Ethernet switch keeps link timing within spec without a separate TCXO. ## Wide supply tolerance and enable/disable control Supply voltage spans 2.25 V to 3.63 V, covering common 2.5 V and 3.3 V rails without an extra LDO. Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the footprint matches industry-standard 5x3.2 mm oscillator pads. The no-lead construction reduces parasitic inductance compared to a leaded can, which matters for the LVDS edge rates at 155.52 MHz.","metaTitle":"DSC1123BI5-155.5200 Microchip XO 155.52 MHz LVDS AEC-Q100","metaDescription":"DSC1123BI5-155.5200: Microchip MEMS XO, 155.52 MHz, LVDS output, ±10 ppm stability, AEC-Q100, -40 to 85°C.
