The DSC1121BI5-024.0000: With a supply voltage range of 2.25V to 3.6V and a maximum supply current of 35 mA, this oscillator fits low-power and general-purpose clocking applications where a quartz crystal would require external load capacitors and a separate oscillator circuit.
6-VDFN package and board layout
Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, the oscillator's Enable/Disable function lets the system gate the clock output without removing power — useful for power-save modes or JTAG clock control. The disable current max is 22 mA, so pulling the enable pin low cuts supply draw compared to the 35 mA active maximum — a meaningful saving in battery-powered designs that sleep the clock tree.
