Title:
Interconnection to Conexant(Rockwell) (CPC5600A1X)
ALL RESISTORS ARE .100W
UNLESS OTHERWISE NOTED
Interconnection diagram is based on the Conexant(Rockwell) RC56D Chip solution.
1. Conexant Chipsets rely on a 6dB loss between MDP and tip and ring. This
is solved by placing the R1, R2, R3, resistor circuit in the Transmit Path
and the use of a single end of the differential receive.
