Data Sheet
Requirement ITU-T I.430, chapter 8.5.1.1b): ’When transmitting a binary zero, the output impedance shall be
> 20
Requirement ITU-T I.430, chapter 8.5.1.1b), Note: ’The output impedance limit shall apply for a nominal load
impedance (resistive) of 50
the peak pulse amplitude for loads equal to the nominal value +/- 10%. The peak amplitude shall be defined
as the the amplitude at the midpoint of a pulse. The limitation applies for pulses of both polarities.’
Test conditions: 1.4 Vpp differential sine wave as input on AIN/BIN with long range (low, critical range).
Versions PEF 8x913 with enhanced performance of the U-interface are tested with tightened limit values
The percentage of the "1 "-values in the PDM-signal.
Interpretation and test conditions: The sum of noise and total harmonic distortion, weighted with a low pass
filter 0 to 80 kHz, is at least 70 dB below the signal for an evenly distributed but otherwise random sequence
of +3, +1, -1, -3.
The signal amplitude measured over a period of 1 min. varies less than 1%.
