75 MHz LVDS clock for serial links
The DSC1103AE1-075.0000T is a 75 MHz LVDS-output MEMS oscillator from Microchip's DSC1103 series. LVDS signalling keeps the edge rates clean for 75 MHz clocking into SerDes, Ethernet PHYs, or FPGA reference inputs — the differential swing rejects common-mode noise that a single-ended CMOS clock would couple onto adjacent traces. Supply range spans 2.25 V to 3.63 V, covering both 2.5 V and 3.3 V rails without an external regulator. The 32 mA maximum supply current at 75 MHz is typical for a MEMS-based LVDS oscillator at this frequency — the MEMS resonator draws less active current than a quartz equivalent at the same output swing.
Standby power-down and temperature range
The output goes high-impedance in standby, so the downstream receiver sees a floating input; a pull-down on the clock line prevents the receiver from oscillating. It fits indoor networking gear, test equipment, and office appliances. For outdoor or under-hood applications, a wider-temperature variant from the DSC1103 family would be needed.
Microchip lists the DSC1103AE1-075.0000T as Active.
