148.3516 MHz LVPECL MEMS oscillator – industrial temperature grade
The DSC1122CI2-148.3516T is a MEMS-based XO (Standard) from Microchip's DSC1122 series, delivering a fixed 148.3516 MHz LVPECL output. Supply voltage spans 2.25V to 3.6V, so it can run from a 2.5V or 3.3V rail without an intermediate regulator.
6-SMD no-lead package – layout and rework considerations
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 no-lead land pattern requires a solder-paste stencil with a 0.15 mm aperture reduction on the centre pad to avoid tombstoning during reflow. The 58 mA max supply current keeps self-heating low, so no thermal via array is needed under the package.
