Notes:

1.

Refer to “AN93: ISOmodem® Chipset Family Designer's Guide” for configuring clock input reset strapping.

2.

Measured at TIP and RING with 600

termination at 1 kHz, as shown in Figure 1 on page 5.

3.

Receive full scale level produces –0.9 dBFS at DTX.

4.

DR = 20 x log |Vin| + 20 x log (rms signal/rms noise). Applies to both transmit and receive paths. Vin = 1 kHz, –3 dBFS.

5.

Vin = 1 kHz, –3 dBFS. THD = 20 x log (rms distortion/rms signal).
