PIN DESCRIPTIONS (1/6)  
Pin  
28-pin 56-pin  
SSOP QFP  
Symbol  
Type  
Description  
Control pin for the center clipping function.  
1
1
NLP  
I
This pin forces the SOUT output to a minimum value when the SOUT  
signal is below –54 dBm0. Effective for reducing low-level noise.  
• Single Chip or Master Chip in a Cascade Connection  
"H": Center clip ON  
"L": Center clip OFF  
• Slave Chip in a Cascade Connection  
Fixed at "L"  
This input signal is loaded in synchronization with the falling edge of the  
INT signal or the rising edge of the RST signal.  
Through mode control.  
2
2
HCL  
I
When this pin is in the through mode,  
RIN and SIN data is output to ROUT and SOUT. At the same time, the  
coefficient of the adaptive FIR filter is cleared.  
• Single Chip or Master Chip in a Cascade Connection  
"H": Through mode  
"L": Normal mode (echo canceler operates)  
• Slave Chip in a Cascade Connection  
Same as master  
This input signal is loaded in synchronization with the falling edge of the  
INT signal or the rising edge of the RST signal.  
AFF coefficient control.  
3
3
ADP  
I
This pin stops updating of the adaptive FIR filter (AFF) coefficient and sets  
the coefficient to a fixed value, when this pin is configured to be the  
coefficient fix mode.  
This pin is used when holding the AFF coefficient which has been once  
converged.  
• Single Chip or Master Chip in a Cascade Connection  
"H": Coefficient fix mode  
"L": Normal mode (coefficient update)  
• Slave Chip in a Cascade Connection  
Fixed at "L"  
This input signal is loaded in synchronization with the falling edge of the  
INT signal or the rising edge of the RST signal.  
4
MS  
I
Select signal.  
This pin selects between the master chip and slave chip when  
used in a cascade connection.  
"L": Single chip or master chip  
"H": Slave chip
