The DSC1101CL2-040.0000: This is a current-production part you can spec into new designs without worrying about a forced migration mid-cycle.
95 µA max supply — low-power clock source
The maximum supply current is 95 µA. The standby (power-down) function lets you cut the clock entirely when the system is idle, pulling the supply current to near zero through the enable pin.
Wide supply range and CMOS output
The 2.25V to 3.6V supply range means this part runs from a 3.3V or 2.5V rail without an extra regulator — useful when the MCU core and I/O are on separate supplies. The CMOS output drives standard logic inputs directly; no level translation needed for most 3.3V or 2.5V logic families.
6-SMD no-lead package — layout notes
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 small footprint leaves room for decoupling caps close to the supply pin, which is good practice for keeping the output jitter low.
