Supply range and power budget for the BOM

Package fit and board-level notes

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm, the part occupies a standard 7050 footprint and is compatible with reflow soldering profiles for lead-free assemblies.

Frequently asked questions

Is DSC1121AI2-148.5000 a direct replacement for a quartz crystal oscillator at 148.5 MHz?

Yes, it is a drop-in MEMS replacement for a standard 148.5 MHz XO with CMOS output. The MEMS base resonator eliminates quartz crystal aging effects and offers better shock/vibration tolerance, but the electrical interface (CMOS levels, enable/disable pin) is identical to a conventional oscillator in the same 6-SMD footprint.

Does DSC1121AI2-148.5000 fit my design for 148.5 MHz with CMOS output?

Yes, this part is specified for 148.5 MHz CMOS output. The enable/disable pin is active-high; leave it floating or tie to VDD if not used.
