Receiver Notes
D
The same type 1:2CT ratio transformer may be
used at the receiver input and transmitter output.
D
R1 and R2 are both 150
for 75
operation, or
240
for 120
operation.
D
Return loss exceeds ITU G.703 specification with
these resistors and a 1:2CT ratio input transformer.
LOS (Loss of Signal) Notes
D
LOSSEL (pin 25) is connected to logic “1” for ITU
G.775 compliant LOS delay, or to logic 0 for user
programmable additional delay.
D
LOSCNT (pin 45) is unconnected when LOSSEL is
logic 1, or connected to an external clock when
LOSSEL is logic 0.
Transmitter Notes
D
Return loss exceeds ETSI 300 166 specification
with a 1:2 ratio transformer.
D
R3 and R4 are always 9.1
for both 75
and 120
applications.
