Buffer inputs to the equalizer network buffer circuit. This circuit  
provides a high impedance load to the transformer termination  
network in order to comply with the required return loss  
specifications. These pins should be connected as shown in  
Figure 17. These pins are electrically equivalent.  
ANDATIN  
16  
Analog serial data input from the equalizer circuit. It must be  
connected to the output of the equalizer circuit as shown in  
Figure 17. When the S3016 is used with a fiber optic receiver,  
this input should be left open and the SERDATIP/N inputs  
should be used.

Equalization select used to select SERDATIP/N or ANDATIN. A  
logic high selects ANDATIN.

signal is lost.

Test clock enable signal, active high, that enables the reference  
clock to be used in place of the VCO for testing. Allows a means  
of testing the functions of the chip without the use of the PLL.  
CMI Select used to select CMI or NRZ. A logic high selects CMI  
mode. Either ANDATIN or SERDATIN may be used as inputs to  
the CMI decoder.  
Reset input for the device, active low. Initializes the device to a  
known state, shuts off SERCLKOP/N, and forces the PLL to  
acquire to the reference clock. A reset of at least 16 ms should  
be applied at power-up and whenever it is necessary to  
reacquire to the reference clock. The S3016 will also reacquire  
to the reference clock if the serial data is held quiescent  
(constant ones or constant zeros) or LOSIN or LOSOPT are  
activated for at least 224 bit intervals.
