That stability is tighter than a typical ±25 ppm quartz oscillator, which matters when the clock drives a SERDES PLL or a high-speed ADC where jitter budget is tight. ## Standby power-down and LVDS drive When active, the LVDS output delivers the 337.6 MHz clock with the differential swing and common-mode voltage defined by the LVDS standard, so it mates directly with FPGA LVDS clock inputs or a downstream LVDS fan-out buffer. The 32 mA max active current is low for a 337.6 MHz LVDS oscillator; the MEMS core draws less than a quartz equivalent at this frequency. ## Package, footprint, and board-level fit The 6-VDFN package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a small footprint that fits under a heatsink or in a tight card-edge area. The supply voltage range (2.25V to 3.63V) covers both 2.5V and 3.3V logic rails without an external regulator, which simplifies the power tree on mixed-voltage boards.","metaTitle":"DSC1103CI5-337.6000T MEMS XO, 337.6 MHz LVDS, ±10 ppm","metaDescription":"Active Microchip DSC1103 series MEMS oscillator, 337.6 MHz LVDS output, ±10 ppm stability, 2.25V-3.63V supply, standby function.

The Standby (Power Down) function disables the output and reduces supply current to 95 µA max. The output goes into high-impedance during standby, so it does not load the downstream clock tree."},{"question":"Can the DSC1103CI5-337.6000T drive standard LVDS inputs at 3.3V?","answer":"Yes. The LVDS output is specified for the full 2.25V to 3.63V supply range, so it drives standard LVDS receivers at 3.3V without a level translator. The differential swing and common-mode voltage meet the LVDS standard across the supply range."},{"question":"Is the DSC1103CI5-337.6000T a drop-in replacement for quartz oscillators?","answer":"Functionally yes — it replaces a 337.6 MHz LVDS quartz oscillator in the same 6-VDFN footprint. The MEMS core offers faster start-up and better vibration resistance than quartz, but the pinout and supply voltage are compatible. Confirm the enable/disable logic polarity matches your design; the DSC1103 uses Standby (Power Down) which is active-low on most variants."},{"question":"What is the standby current consumption of the DSC1103CI5-337.6000T?","answer":"The standby (disable) supply current is 95 µA max. When active, the supply current is 32 mA max at 337.6 MHz LVDS output."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1103CI5-337.6000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1103CI5-337.6000T when reusing this data.
