No quartz crystal to crack on a drop. ## HCSL output and supply range — what the downstream receiver needs HCSL (High-Speed Current Steering Logic) is the standard output for PCIe reference clocks — the differential swing and common-mode voltage are set to drive a 50-Ω terminated line directly. If your receiver expects LVDS or LVPECL, this part won't swing the right levels without an external level translator. The supply range is 2.25 V to 3.6 V, which covers the common 2.5 V and 3.3 V rails. That 20 mA saving matters in a battery-powered design where the clock is gated between bursts. ## Package and footprint — 6-SMD no-lead, 5.0 × 3.2 mm The 6-SMD no-lead package measures 5.00 mm × 3.20 mm with a seated height of 0.90 mm — a standard footprint that matches many quartz oscillators in the same form factor. The pad layout is the same as a typical 5.0 × 3.2 mm XO; if you're swapping a quartz part in this package, the PCB doesn't need a spin.","metaTitle":"DSC1124BI5-148.3516 MEMS XO, 148.3516 MHz, HCSL, ±10 ppm","metaDescription":"Microchip DSC1124BI5-148.3516: 148.3516 MHz MEMS XO, HCSL output, ±10 ppm stability, industrial temp range.

The MEMS resonator is electrically equivalent at the output pins; the supply range and enable logic are the same. Confirm the output type — if the original quartz part is LVDS or LVPECL, this HCSL output will not drive the receiver without a level shifter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1124BI5-148.3516","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1124BI5-148.3516 when reusing this data.
