Master Mode
This is a mode activated by strapping the MASTER pin to a ‘1’ on
the ISL76321 on the remote side of the link from the
microcontroller. This is a virtual extension of the I2C interface
across the link that allows the local processor to read and write
slave devices connected to the remote side SERDES I2C bus. No
additional wires or components are needed other than the serial
link. The I2C commands and data are transferred during video
blanking causing no interruptions in the video data. In Master
mode, the data is transported across the link by the Side Channel
so the maximum throughput achievable would be the same. The
SCL and SDA frequency is adjustable through the programming
of a register. If a SERDES chip is configured as a master it is no
longer available for communication by a local microcontroller. It
is assumed that the SERDES is the only master.
Exposed Pad
While it is not a required electrical connection, it is
recommended that the exposed pad on the bottom of the
package be soldered to the circuit board. This will ensure that the
full power dissipation of the package can be utilized. The pad
should be connected to ground and not left floating. For best
thermal conductivity, 16 vias should connect the footprint for the
exposed pad on the circuit board to the ground plane. This
connection is not required for basic operation of the chip.
