5.1.3 Operating Characteristics

For the following conditions unless otherwise specified:

VDD = 5.0V at TAMB = 25°C

Clock Frequency = 4.0MHz, 0dB reference = 300mVRMS (Note: Measured at pin 18, the FILTR output. This pin must not

exceed 300mVRMS at 1kHz in Tx and 500mVRMS at any frequency in Rx, or clipping may occur. The difference in levels is

due to the pre-emphasis filter in the Tx path.
