PACKAGE POWER DISSIPATION vs AMBIENT TEMPERATURE 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. Page 8 of 10 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 FN6278 Rev 0.00 September 21, 2006 Page 9 of 10 ISL59117 Wafer Level Chip Scale Package (WLCSP) W3x3.9A 3x3 ARRAY 9 BALL WAFER LEVEL CHIP SCALE PACKAGE (For ISL59116, ISL59117 Only) E PIN A1 ID AREA SYMBOL MILLIMETERS NOTES A 0.62 +0.05 -0.08 - A1 0.24 ±0.025 - A2 0.38 REF. - b 0.32 ±0.03 - bb 0.30 REF. - D 1.45 ±0.05 - D1 1.00 BASIC - E 1.45 ±0.05 - E1 1.00 BASIC - D TOP VIEW bb A2 A A1 b e 0.50 BASIC - SD 0.00 BASIC - N 9 3 Rev. 1 6/06 SIDE VIEW NOTES: 1.
