V
REF
M3
DC-restore clamp reference input.
In an AC-coupled configuration
(DC-Restore clamp enabled), the sync
tip of composite video inputs will be
restored to this level. Set to 0.3 to 0.7V
for optimum performance.
In an DC-coupled configuration
(DC-Restore clamp disabled), this pin
should be tied to ground.
Never let the V
REF
pin float!
A floating
VREF pin drifts high (and if the clamp
function is enabled) will cause all of the
outputs to simultaneously try to drive
~4V DC into their 150
loads.
SLATCH
J3
Serial Latch. Serial data is latched into
ISL59532 on rising edge of SLATCH.
SCLK
K3
Serial data clock
SDI
L3
Serial data input
SDO
G3
Serial data output. Can be tied to SDI of
another ISL59532 to enable daisy-
chaining of multiple devices.
RESET
H3
Reset input. Pull high then low to reset
device, but not needed in normal opera-
tion. Tie to ground in final application.
V
SDO
D3
Power supply for SDO pin. Tie to +5V
for a 0 to 5V SDO output signal swing.
V
S
+5V power supply
GND
Ground
NC
No Connect -
Do not electrically con-
nect to anything, including ground
.
