In single voltage supply mode (see
System interface at 16 MHz; all-ones data; T
To achieve maximum receiver sensitivity of -43 dB (E1) take special care on sufficient attenuation of crosstalk
between Rx and Tx on board (e.g. in transformer) and run sequence as specified in
Differential input voltage between pins RL1 and RL2
Values only valid for LIM0.EQON = 1, LOS detection limits set to PCR = 15 H , PCD = A H , applied signal
sequence +1,0,-1,0,...
Parameter not tested in production
Value measured in production to fulfil ITU-T G.775
