Description
ODQTE60M is an enabled crystal oscillator, output driver pad piece that runs over a frequency range of 20 - 60 MHz.
QI is the input from the IDQC3. E is the oscillator high input enable. PADM is the bond pad to Xtal-out.

Design Notes:
The ODQTE60M is the output cell of a two cell oscillator circuit. The QI pin is to be connected the QO pin of the IDQC3 oscillator input receiver piece. Two package pins
are required to create a complete oscillator.
