Triple Channel Video Driver with LPF
The ISL59117 is a triple channel reconstruction filter with a
-3dB roll-off frequency of 9MHz. Operating from single
supplies ranging from +2.5V to +3.6V and drawing only
3.9mA quiescent current, the ISL59117 is ideally suited for
low power, battery-operated applications. Additionally,
enable pins shut the part down in under 14ns.
The ISL59117 is designed to meet the needs for very low
power and bandwidth required in battery-operated
communication, instrumentation, and modern industrial
applications such as video on demand, cable set-top boxes,
MP3 players, and HDTV. The ISL59117 is offered in a
space-saving chipscale package guaranteed to a 0.57mm
maximum height constraint and specified for operation from
-40°C to +85°C temperature range.

Application Information
The Sallen Key Low Pass Filter
The ISL59117 is a single-supply rail-to-rail triple (one s-video
channel and one composite channel) video amplifier with
internal sync tip clamps, a typical -3dB bandwidth of 9MHz and
slew rate of about 40V/µs. This part is ideally suited for
applications requiring high composite and s-video performance
with very low power consumption. As the performance
characteristics and features illustrate, the ISL59117 is
optimized for portable video applications.
The Sallen Key is a classic low pass configuration. This provides
a very stable low pass function, and in the case of the ISL59117,
a three-pole roll-off at 9MHz. The three-pole function is
accomplished with an RC low pass network placed in series with
and before the Sallen Key. The first pole is formed by an RC
network, with poles two and three generated with a Sallen Key,
creating a nice three-pole roll-off at 9MHz.
Internal Sync Clamp
The ISL59117 can be AC or DC coupled to its output. When
AC coupling, a 220µF coupling capacitor is recommended to
ensure that low frequencies are passed, preventing video “tilt”
or “droop” across a line.
Embedded video DACs typically use ground as their most
negative supply. This places the sync tip voltage at a minimum
of 0V. Presenting a 0V input to most single supply amplifiers
will saturate the output stage of the amplifier resulting in a
clipped sync tip and degraded video image.
The ISL59117 features an internal sync clamp and offset
function that level shifts the entire video signal to the optimum
level before it reaches the amplifiers’ input stage. These
features also help avoid saturation of the output stage of the
amplifier by setting the signal closer to the best voltage range.
The simplified block diagram on the front page shows the basic
operation of the ISL59117’s sync clamp. The Y and CVBS
inputs’ AC-coupled video sync signal is pulled negative by a
current source at the input. When the sync tip goes below the
comparator threshold, the comparator output goes high, pulling
up on the input through the diode, forcing current into the
coupling capacitor until the voltage at the input is again 0V, and
the comparator turns off. This forces the sync tip clamp to
always be 0V, setting the offset for the entire video signal. The
C channel is slaved to the Y channel and clamped to a 500mV
level.
FN6278 Rev 0.00
September 21, 2006
Output Coupling
The ISL59117’s internal sync clamp makes it possible to DC
couple the output to a video load, eliminating the need for any
AC coupling capacitors, saving board space, cost, and
eliminating any “tilt” or offset shift in the output signal. The
trade off is larger supply current draw, since the DC component
of the signal is now dissipated in the load resistor. Typical load
current for AC coupled signals is 5mA compared to 10mA for
DC coupling.
Output Drive Capability
The ISL59117 does not have internal short circuit protection
circuitry. If the output is shorted indefinitely, the power
dissipation could easily overheat the die or the current could
eventually compromise metal integrity. Maximum reliability is
maintained if the output current never exceeds ±40mA. This
limit is set by the design of the internal metal interconnect.
Note that for transient short circuits, the part is robust.
Short circuit protection can be provided externally with a back
match resistor in series with the output placed close as
possible to the output pin. In video applications this would be a
75 resistor and will provide adequate short circuit protection
to the device. Care should still be taken not to stress the device
with a short at the output.

ISL59117
Power Dissipation
With the high output drive capability of the ISL59117, it is
possible to exceed the +125°C absolute maximum junction
temperature under certain load current conditions. Therefore, it
is important to calculate the maximum junction temperature for
an application to determine if load conditions or package types
need to be modified to assure operation of the amplifier in a
safe operating area.
The maximum power dissipation allowed in a package is
determined according to:
T JMAX – T AMAX
PD MAX = -------------------------------------------- JA
Where:
TJMAX = Maximum junction temperature
Power Supply Bypassing Printed Circuit Board
Layout
As with any modern operational amplifier, a good printed circuit
board layout is necessary for optimum performance. Lead
lengths should be as short as possible. The power supply pin
must be well bypassed to reduce the risk of oscillation. For
normal single supply operation, a single 4.7µF tantalum
capacitor in parallel with a 0.1µF ceramic capacitor from VS+ to
GND will suffice.
Printed Circuit Board Layout
For good AC performance, parasitic capacitance should be
kept to minimum. Use of wire wound resistors should be
avoided because of their additional series inductance. Use of
sockets should also be avoided if possible. Sockets add
parasitic inductance and capacitance that can result in
compromised performance.
TAMAX = Maximum ambient temperature
JA = Thermal resistance of the package
The maximum power dissipation actually produced by an IC is
the total quiescent supply current times the total power supply
voltage, plus the power in the IC due to the load, or:
for sourcing:
V OUT
PD MAX = V S  I SMAX +  V S – V OUT   ---------------R
L
for sinking:
PD MAX = V S  I SMAX +  V OUT – V S   I LOAD
Where:
VS = Supply voltage
ISMAX = Maximum quiescent supply current
VOUT = Maximum output voltage of the application
RLOAD = Load resistance tied to ground
ILOAD = Load current
