ISL59123
FN6432.1
Triple Channel Video Driver with LPF
Features
The ISL59123 is a triple channel reconstruction filter with a
-3dB roll-off frequency of 18MHz. Operating from single
supplies ranging from +2.5V to +3.6V and sinking a low 4mA
quiescent current, the ISL59123 is ideally suited for low
power, battery-operated applications. An enable pin allows
the part to be placed in a 500nA shutdown mode in less than
30ns.
• 3rd order 18MHz reconstruction filter
The ISL59123 is designed to meet the needs for extremely
low power and bandwidth requirements in battery-operated
communication, instrumentation, and modern industrial
applications such as video on demand, cable set-top boxes,
MP3 players, and HDTV. The ISL59123 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.

Where:
Application Information
The ISL59123 is a single-supply rail-to-rail triple video lowpass filter and amplifier with a -3dB bandwidth of 18MHz. It
provides anti-aliasing for component, s-video, and
composite video signals. Its small size and low power make
the ISL59123 ideal for portable video applications.
The Sallen Key Low Pass Filter
The Sallen Key is a classic low pass configuration. This
provides a very stable low pass function, and in the case of
the ISL59123, a three-pole roll-off at 18MHz. 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 (including the impedance of the
source driving the ISL59123), with poles two and three
generated by a Sallen Key, creating a three-pole roll-off
characteristic at 18MHz.
TJMAX = Maximum junction temperature
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 use Equation 2:
V OUT
PD MAX = V S  I SMAX +  V S – V OUT   ---------------R
L
(EQ. 2)
for sinking use Equation 3:
PD MAX = V S  I SMAX +  V OUT – V S   I LOAD
(EQ. 3)
Where:
Output Coupling
The ISL59123 can be AC or DC coupled to its output. When
AC coupled, a 220µF coupling capacitor is recommended to
ensure that low frequencies are passed, preventing video
“tilt” or “droop” across a line.
Output Drive Capability
The ISL59123 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.
Power Dissipation
With the high output drive capability of the ISL59123, 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.
VS = Supply voltage
ISMAX = Maximum quiescent supply current
VOUT = Maximum output voltage of the application
RLOAD = Load resistance tied to ground
ILOAD = Load current
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 VDD 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.
The maximum power dissipation allowed in a package is
determined according to Equation 1:
T JMAX – T AMAX
