Enabling Outputs
The output enable control word is used to enable individual outputs. There are 32 channels to configure, so this is accomplished by
writing 4 serial words, each controlling a bank of eight outputs at a time. The bank is selected by bits B9 and B8. The output enable
control word format is:
Setting the O
N
bit = 0 tri-states the output. Setting the O
N
bit = 1 enables the output if the Global Output Enable bit is also set (the
individual output enable bits are ANDed with the Global Output Enable bit before they are sent to the output stage).
Setting the Gain
The gain of each output may be set to x1 or x2 using the Gain Set word. It is in the same format as the output enable control word:
Set G
N
= 0 for a gain of x1 or 1 for a gain of x2.
Broadcast Mode
The Broadcast Mode routes one input to all 32 outputs. The broadcast control word is:
I
4
:I
0
form the 5-bit word indicating the input channel (0 to 31) to be sent to all 32 outputs. Set the Enable Broadcast bit (B0) = 1 to
enable Broadcast Mode, or to 0 to disable Broadcast Mode. When Broadcast Mode is disabled, the previous channel assignments
are restored.
Control Word
The ISL59532’s power-on reset disables all outputs and places the part in a low-power standby mode. To enable the device, the
following control word should be sent:
The Clamp bit enables the input clamp function, forcing the AC-coupled signal’s most negative point to be equal to V
REF
.
Note:
The Clamp bit turns the DC-Restore clamp function on or off for
all
channels - there is no DC-Restore on/off control for
individual channels. The DC-Restore function only works with signals with sync tips (composite video). Signals that do not have
sync tips (the Chroma/C signal in s-video and the Pb, Pr signals in Component video), will be severely distorted if run through a
DC-Restore/clamp function.
