The footprint matches the industry-standard 3.2x2.5 mm MEMS oscillator land pattern – a layout designed for a SiTime or Abracon part in the same package will accept this Microchip DSC1122CI5 without a board spin.","metaTitle":"DSC1122CI5-068.0000T – 68 MHz LVPECL MEMS Oscillator","metaDescription":"Microchip DSC1122CI5-068.0000T: 68 MHz XO, LVPECL output, ±10 ppm stability, 2.25-3.6 V supply, -40 to 85 °C, 6-SMD.

The LVPECL output swing scales with VCC; at 2.5 V the differential swing is approximately 700 mV, still within the receiver's input common-mode range."},{"question":"What is the closest pin-compatible alternative to DSC1122CI5-068.0000T?","answer":"The DSC1122 series uses the standard 6-SMD 3.2x2.5 mm MEMS oscillator footprint. Pin-compatible alternatives include SiTime SiT9121 or Abracon ASDMB series parts with the same package, supply voltage, and LVPECL output – but confirm the frequency (68 MHz) and stability (±10 ppm) are available in the target alternative."},{"question":"How do I enable/disable the output on DSC1122CI5?","answer":"The Enable/Disable pin (pin 1 on the 6-SMD package) controls the output. Pull it high (to VCC) or leave it open for normal operation; pull it low (to GND) to disable the output into high-impedance state. When disabled, the supply current drops to 22 mA max."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CI5-068.0000T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CI5-068.0000T when reusing this data.
