Spurious Out-of-Band Signals at the Analog Output
With PCM code words representing a sine wave signal in the range of 300 Hz to 3400 Hz at a level of 0 dBm0 applied to the
digital input, the level of the spurious out-of-band signals at the analog output is less than the limits shown below.
With code words representing any sine wave signal in the range 3.4 kHz to 4.0 kHz at a level of 0 dBm0 applied to the digital
input, the level of the signals at the analog output are below the limits in
signals between 3400 Hz and 4600 Hz is given by the formula:
Level (dBm0)
