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 opti-
mum performance.
In an DC-coupled configuration
(DC-Restore clamp disabled), this pin
should be tied to ground.
Do not let the V_REF pin float! A
floating V_REF 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 150Ω 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.
