At 400 MHz LVDS, this oscillator serves as the reference clock for 10GbE PHYs, FPGA transceivers, and SERDES devices that need a low-jitter differential input — the LVDS output swings 350 mV typical into a 100-Ω termination, which most high-speed SERDES blocks accept directly. The 2.25V to 3.63V supply range means the oscillator can run from a 2.5V or 3.3V rail without an extra LDO — useful when the FPGA bank voltage is 2.5V and the rest of the board is 3.3V, because the same part number covers both builds. ## 6-SMD no-lead package and board integration Housed in a 7.00 mm × 5.00 mm 6-SMD no-lead package with a seated height of 0.90 mm — the footprint matches industry-standard 7×5 mm oscillator pads, so it drops onto existing layouts without a board spin.","metaTitle":"DSC1103NI1-400.0000 Microchip 400 MHz LVDS MEMS Oscillator","metaDescription":"Active Microchip DSC1103NI1-400.0000 XO (Standard) LVDS output, 400 MHz, MEMS resonator, -40°C to 85°C, 2.25V-3.63V supply.

The LVDS output is a differential pair that swings 350 mV into 100 Ω; it does not swing rail-to-rail, so it is not a 3.3V CMOS signal but is fully compatible with LVDS receivers on FPGAs and PHYs."},{"question":"What does the standby function do on the DSC1103NI1-400.0000?","answer":"When the standby pin is asserted, the oscillator stops and the output goes into high-impedance, drawing 95 µA max from the supply. This lets you gate the clock for power saving or share a single LVDS trace among multiple oscillators by enabling only one at a time."},{"question":"Can the DSC1103NI1-400.0000 replace a standard 400 MHz LVDS crystal oscillator?","answer":"Yes, if the existing oscillator is a 7×5 mm 6-SMD no-lead LVDS part running from 2.25V to 3.63V. The MEMS resonator gives tighter frequency stability (±50 ppm) over temperature than many quartz-based XOs, and the standby function adds a power-down feature that quartz parts often lack. Pin compatibility depends on the specific pinout — confirm the enable and supply pin assignments against the existing footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1103NI1-400.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1103NI1-400.0000 when reusing this data.
