Rated over -40°C to 85°C with ±50 ppm frequency stability, it holds the clock edge within tight tolerance across the industrial temperature band — relevant for 10GbE, SFP+ modules, and FPGA reference clocks where the LVDS pair drives a differential input directly. ## 3.3V supply, enable/disable function, 6-VDFN footprint Operates from a single 3.3V supply rail, drawing 32 mA max when enabled and 22 mA max when disabled — the enable/disable pin lets the system power down the oscillator for low-power sleep modes without a separate clock buffer. Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm x 0.90 mm, the DSC1123DI1-233.3333 fits dense PCB layouts where board space is tight — the 0.50 mm pitch requires careful fan-out but is manageable on a standard 4-layer stack. ## Active production — sourced per RFQ","metaTitle":"DSC1123DI1-233.3333 Microchip 233.3333 MHz LVDS MEMS XO","metaDescription":"Microchip DSC1123DI1-233.3333: 233.3333 MHz LVDS XO, MEMS resonator, ±50 ppm stability, -40°C to 85°C, 6-VDFN.

The LVDS output is self-biased and drives a 100-ohm differential termination at the receiver."},{"question":"What is the function of the enable pin on DSC1123DI1-233.3333?","answer":"The enable/disable function allows the oscillator output to be tri-stated. When disabled, the supply current drops to 22 mA max, enabling power savings in sleep or standby modes without removing the 3.3V rail."},{"question":"Is DSC1123DI1-233.3333 compatible with a 2.5V supply?","answer":"No — the specified supply voltage is 3.3V. Operating at 2.5V is outside the datasheet range and may cause the LVDS output to fall out of common-mode or amplitude specification. Use the DSC1123 series variant rated for 2.5V if needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123DI1-233.3333","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123DI1-233.3333 when reusing this data.
