THEORY OF OPERATION
INTRODUCTION
The ADN8102 is a quad, bidirectional cable and backplane
equalizer that provides both input equalization and output pre-
emphasis on both the line card and cable sides of the device.
The device supports full loopback and through connectivity
of the two unidirectional half-links, each consisting of four
differential signal pairs.
The ADN8102 offers extensively programmable output levels
and pre-emphasis as well as the ability to disable the output
current. The receivers integrate a programmable, multizero
equalizer transfer function that is optimized to compensate
either typical backplane or typical cable losses.
The I/O on-chip termination resistors are terminated to user-
settable supplies to support dc coupling in a wide range of logic
styles. The ADN8102 supports a wide core supply range; VCC
can be set from 1.8 V to 3.3 V. These features, together with
programmable output levels, allow for a wide range of dc- and
ac-coupled I/O configurations.
The ADN8102 supports several control and configuration
modes, as shown in Table 5. The pin control mode offers access
to a subset of the total feature list but allows for a much
simplified control scheme. The primary advantage of using the
serial control interface is that it allows finer resolution in setting
receive equalization, transmitter preemphasis, loss-of-signal
(LOS) behavior, and output levels.
By default, the ADN8102 starts in pin control mode. Strobing
the RESET pin sets all on-chip registers to their default values
and uses pins to configure loopback, PE, and EQ levels. In
mixed mode, loopback is still controlled through the external
pin. The user can override PE and EQ settings in mixed mode.
In serial mode, all functions are accessed through registers, and
the control pin inputs are ignored, except RESET .
The ADN8102 register set is controlled through a 2-wire, I2C
interface. The ADN8102 acts only as an I2C slave device. The 7-bit
slave address for the ADN8102 I2C interface contains the static
value b10010 for the upper four bits. The lower two bits are
controlled by the input pins, ADDR[1:0]
