The MEMS resonator gives it an edge over quartz in shock and vibration environments — no start-up reliability concerns from a crystal blank under mechanical stress. LVPECL output means the device drives the differential clock inputs found on high-speed FPGAs, 10G Ethernet PHYs, and SerDes transceivers directly, without external level translation. For outdoor base stations or engine-bay electronics, a wider-temperature variant from the DSC1122 family would be needed. ## Package and layout – 6-SMD no-lead Housed in a 6-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The small footprint frees board area for dense routing around the clock tree.","metaTitle":"DSC1122CE5-047.9980 MEMS XO – 47.998 MHz LVPECL, ±10 ppm","metaDescription":"Microchip DSC1122CE5-047.9980: 47.998 MHz LVPECL MEMS oscillator, ±10 ppm stability, 2.25–3.6 V supply, -20 to +70 °C.

The evidence does not list a specific RoHS certificate, but the product is a lead-free MEMS oscillator in a 6-SMD package — confirm the latest manufacturer statement on the Microchip website for your compliance audit."},{"question":"Can the DSC1122CE5-047.9980 replace a standard quartz oscillator on my board?","answer":"Yes, if the board expects a 47.998 MHz LVPECL differential clock and the supply voltage is within 2.25–3.6 V. The MEMS resonator is a drop-in replacement for quartz in the same 6-SMD footprint — no external load capacitors are needed, unlike a quartz crystal oscillator that requires them. The Enable/Disable pin may need a pull-up or pull-down depending on your existing circuit."},{"question":"Does the DSC1122CE5-047.9980 require an external capacitor?","answer":"No external load capacitors are needed. As a MEMS oscillator, the output is a full-rail LVPECL signal — the internal MEMS resonator and PLL generate the frequency without the external feedback network that a quartz crystal requires."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1122CE5-047.9980","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1122CE5-047.9980 when reusing this data.
