LVDS is a differential pair that rejects common-mode noise on long PCB traces, making this oscillator a direct fit for high-speed serial interfaces — think 1 GbE, SATA, or FPGA transceiver reference clocks — where a single-ended CMOS clock would radiate or pick up noise. ## Standby mode and supply tolerance for power-sensitive designs The 2.25V to 3.63V supply range means the oscillator runs from either a 2.5V or 3.3V rail without an extra LDO. If the 3.3V rail dips to 2.5V during a load transient, the oscillator keeps running — no clock glitch that could corrupt a frame or crash a PLL.","metaTitle":"DSC1103DL5-159.3750T MEMS XO, 159.375 MHz LVDS, ±10 ppm","metaDescription":"Microchip DSC1103DL5-159.3750T: 159.375 MHz LVDS MEMS oscillator, ±10 ppm stability, 2.25V-3.63V supply, standby mode.

The supply range is 2.25V to 3.63V, so a 3.3V rail is within spec. No external LDO is needed if the rail stays inside that window."},{"question":"Can the DSC1103DL5 directly replace a 159.375 MHz quartz oscillator?","answer":"Functionally yes — same frequency, same LVDS output type. The MEMS-based DSC1103 series is a drop-in replacement for a quartz XO in the same 6-VDFN footprint, with the advantage of no crystal load-cap selection and better shock/vibration tolerance. Confirm the pinout matches your existing quartz oscillator's pin 1 assignment before committing."},{"question":"What is the footprint of the DSC1103DL5-159.3750T?","answer":"6-VDFN package, 2.50mm x 2.00mm body, 0.90mm seated height. The 0.098\" x 0.079\" footprint is standard for small-form-factor MEMS oscillators — hand-solderable with a fine-tip iron and flux, though a hot-air rework station is easier for consistent wetting on the ground pad."},{"question":"Does the DSC1103DL5 have a standby mode?","answer":"Yes. The Standby (Power Down) function disables the output and drops supply current to 95 µA max. Pull the pin low to enable the oscillator; pull it high (or leave floating with an internal pull-up) for normal operation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1103DL5-159.3750T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1103DL5-159.3750T when reusing this data.
