244 MHz LVDS MEMS oscillator — industrial clock source
The DSC1103CI2-244.0000 is a 244 MHz LVDS-output MEMS oscillator from Microchip's DSC1103 family, housed in a 3.20 mm × 2.50 mm 6-SMD no-lead package.
Frequency stability and temperature range
At 244 MHz, a ±25 ppm window equals roughly ±61 kHz of absolute frequency error — enough margin for most 10 GbE and SerDes PLLs to lock without hitting the tracking limit. The -40°C low end covers outdoor telecom cabinets and unheated factory floors; the 85°C top suits engine-bay or enclosure-adjacent placement.
The 32 mA max at 244 MHz is competitive for an LVDS output; the thermal rise in the 3.2×2.5 mm package stays low enough that no special pad layout is needed beyond the usual ground vias under the no-lead land pattern.
Microchip lists the DSC1103CI2-244.0000 as Active.
