The 6-SMD no-lead package measures 2.50 mm × 2.00 mm with a seated height of 0.90 mm — small enough for space-constrained designs like small-form-factor NICs or industrial sensor modules.

MEMS oscillators typically start up faster (sub-millisecond vs millisecond for quartz), survive higher shock and vibration, and have a smaller footprint for the same frequency stability. The trade-off is that the phase-noise floor at very close-in offsets (below 1 kHz) can be higher than a good quartz OCXO, but for a 27 MHz HCSL reference driving a SerDes PLL, the ±50 ppm stability and jitter are adequate."},{"question":"What is the difference between the DSC1104 and DSC1124 series?","answer":"The DSC1104 and DSC1124 share the same MEMS resonator and package options, but the DSC1124 adds a spread-spectrum modulation feature to reduce EMI. The DSC1104 does not have spread spectrum — it outputs a clean fixed-frequency HCSL clock. If EMI reduction is needed, the DSC1124 is the functional alternative; otherwise the DSC1104 is the lower-cost choice for a standard HCSL reference."},{"question":"Is the DSC1104DL1-027.0000 RoHS compliant?","answer":"The part number does not include a RoHS indicator suffix, but Microchip's DSC1104 series is manufactured RoHS-compliant and lead-free per the standard product marking. The 6-SMD no-lead package is compatible with lead-free reflow profiles."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1104DL1-027.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1104DL1-027.0000 when reusing this data.
