The DSC1101BI3-013.5600T is a 13.56 MHz XO (Standard) oscillator from Microchip's DSC1101 series, built around a MEMS resonator rather than a quartz crystal. The CMOS output swings rail-to-rail, making it a direct drop-in for MCU clock inputs, Ethernet PHY reference clocks, or any digital logic that expects a square-wave clock.
Industrial temperature grade and standby power savings
Active draw is 35 mA max at full speed.
6-VDFN package and supply flexibility
Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the DSC1101BI3-013.5600T is a surface-mount oscillator that fits tight board stacks. Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without a separate regulator. Frequency stability is ±20 ppm — tight enough for UART bit-rate accuracy and most MCU PLL references.
The base product number is DSC1101; the full order code includes the frequency, stability grade, and packaging (Tape & Reel,).
