Rated across -40°C to +85°C with ±10 ppm frequency stability, it holds the clock edge tight enough for 1 GbE, PCIe Gen 1, or SATA reference clock applications without a separate TCXO. Supply voltage spans 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail directly — no extra LDO needed for the oscillator alone. At 32 mA max during active operation, the 300 MHz LVDS oscillator draws less than many fixed-frequency quartz oscillators at the same speed, keeping the local thermal rise low on a dense board. ## 6-SMD, No Lead package and board fit Housed in a 3.20 mm x 2.50 mm 6-SMD, No Lead package with a seated height of 0.90 mm max — this is the standard 3.2×2.5 mm footprint that matches many LVDS oscillators, so a layout designed for a SiTime or Epson part often accepts the DSC1103 without a pad change. Surface-mount only; the small land pattern suits tight card-edge designs or multi-gigabit switch line cards where board real estate is at a premium.","metaTitle":"DSC1103CI5-300.0000 – 300 MHz LVDS MEMS Oscillator, ±10 ppm","metaDescription":"Active XO (Standard) from Microchip, 300 MHz LVDS output, ±10 ppm stability, -40 to +85°C.

The LVDS differential pair provides clean edge rates for high-speed serial interfaces and low EMI compared to single-ended CMOS clocks at this frequency."},{"question":"Does the DSC1103CI5-300.0000 support a standby mode?","answer":"Yes — the function is listed as Standby (Power Down). When the enable pin is de-asserted, the output goes into high impedance and the supply current drops to 95 µA max, allowing the system to gate the clock without a separate load switch."},{"question":"What supply voltage range does the DSC1103CI5-300.0000 accept?","answer":"It operates from 2.25V to 3.63V, covering both 2.5V and 3.3V rails. No external regulator is needed if the board already has one of those rails."},{"question":"Can I get the datasheet for the DSC1103CI5-300.0000?","answer":"The datasheet is available from Microchip under the base product number DSC1103.
