Notes:
1. For default 2G ASH control mode operation under FCC 15.249 regulations, a TXMOD resistor value of 22K is typically required.
2. When using internal data and clock recovery, a THLD1 value of 47K is recommended to minimize start vector “nuisance tripping” due
to random noise.
CAUTION: Electrostatic Device. Observe precautions when handling.
