Serial Interface
The IC operating modes can be controlled via the 3-wire
serial interface or via the three external control lines provided
(TX_ENAB, RX_ENAB, SYN_ENAB). The three external
control lines allow mode control of the IC if the baseband con-
troller cannot access the serial interface between slots. In either
case the 3-wire serial interface is used to program the channel
number. Detailed below is the register setup and the serial
interface operation.
The serial interface consists of a 16-bit shift register and two
registers for configuration of the IC and mode control. This
allows mode control of the IC with a single 16-bit write. DATA
is the serial data input (data MSB first), CLK is the shift regis-
ter clock (positive edge trigger), EN (positive edge trigger) is the
serial interface enable. All internal register values are retained
when sections of the IC are powered down. Figure 3 shows the
timing diagram for the serial interface.

The Least Significant Bit of the serial control word selects either
the “one-time setup” register or the operating mode register,
with the remaining 15 bits as data. Table II below details the
internal IC register mapping.

AD6411 INITIAL SETUP
On power-up the state of the IC is
not
defined. A one-time setup
register must be loaded through the serial interface port, and is
selected when the LSB of the serial word is 0. After this one-
time setup, a single serial word controls operation of the IC.
