Data Sheet
Echo Canceller A, Error Peak Detect Register 1
Echo Canceller B, Error Peak Detect Register 1
These peak detector registers allow the user to monitor the error signal peak level. The information is in 16-bit 2’s complement
linear coded format presented in two 8 bit registers for each echo canceller. The high byte is in Register 2 and the low byte is in
Register 1.
Echo Canceller A, Rin Peak Detect Register 2
Echo Canceller B, Rin Peak Detect Register 2
RP
RP
These peak detector registers allow the user to monitor the receive in signal (Rin) peak signal level. The information is in 16-bit 2’s
complement linear coded format presented in two 8 bit registers for each echo canceller. The high byte is in Register 2 and the low
byte is in Register 1.
Echo Canceller A, Sin Peak Detect Register 2
Echo Canceller B, Sin Peak Detect Register 2
SP
SP
These peak detector registers allow the user to monitor the send in signal (Sin) peak signal level. The information is in 16-bit 2’s
complement linear coded format presented in two 8 bit registers for each echo canceller. The high byte is in Register 2 and the low
byte is in Register 1.
