Application Information General The ISL59444 is a 4: mux that is ideal as a matrix element in high performance switchers and routers. The ISL59444 is optimized to drive a 2pF in parallel with a 5Ω load. The capacitance can be split between the PB capacitance an and external load capacitance. Their low input capacitance and high input resistance provide excellent 5Ω or 75Ω terminations. apacitance at the Output The output amplifier is optimized for capacitance to ground ( L ) directly on the output pin. Increased capacitance causes higher peaking with an increase in bandwidth. The optimum range for most applications is ~.pf to ~6pF. The optimum value can be achieved through a combination of P board trace capacitance ( T ) and an external capacitor ( OUT). A good method to maintain control over the output pin capacitance is to minimize the trace length ( T ) to the next component, and include a discrete surface mount capacitor ( OUT ) directly at the output pin. For large signal applications where overshoot is important the circuit in Figure 24B should be used. The series resistor (R S ) and capacitor ( L ) form a low pass network that limits system bandwidth and reduces overshoot. The component values shown result in a typical pulse response shown in Figure 2. Ground onnections For the best isolation and crosstalk rejection, the GND pin and NI pins must connect to the GND plane. The NI pins are placed on both sides of the input pins. These pins are not internally connected to the die. It is recommended this pin be tied to ground to minimize crosstalk. ontrol Signals S, S, HIZ - These pins are, TTL/MOS compatible control inputs. The S, S pins select which one of the inputs connect to the output. The HIZ pin is used to three-state the output amplifiers. For control signal rise and fall times less than ns the use of termination resistors close to the part will minimize transients coupled to the output. HIZ State An internal pull-down resistor connected to the HIZ pin ensures the device will be active with no connection to the HIZ pin. The HIZ state is established within approximately 3ns by placing a logic high (>2V) on the HIZ pin. If the HIZ state is selected, the output is a high impedance.4mω. Use this state to control the logic when more than one mux shares a common output. In the HIZ state the output is three-stated, and maintains its high Z even in the presence of high slew rates. The supply current during this state is basically the same as the active state. Latch State The latched control signals allow for synchronized channel switching. When LE is low the master control latch loads the next switching address (S, S), while the closed (assuming LE2 is the inverse of LE) slave control latch maintains the current state. LE2 switching low closes the master latch (with previous assumption), loads the now open slave latch, and switches the crosspoint to the newly selected channel. hannel selection is asynchronous (changes with any control signal change) if both LE and LE2 are low. Power-Up onsiderations The ESD protection circuits use internal diodes from all pins the and supplies. In addition, a dv/dt triggered clamp is connected between the and pins, as shown in the Equivalent ircuits through 4 section of the Pin Descriptions on page 2. The dv/dt triggered clamp imposes a maximum supply turn-on slew rate of V/µs. Damaging currents can flow for power supply rates-of-rise in excess of V/µs, such as during hot plugging. Under these conditions, additional methods should be employed to ensure the rate of rise is not exceeded. onsideration must be given to the order in which power is applied to the and pins, as well as analog and logic input pins. Schottky diodes (Motorola MBR55T or equivalent) connected from to ground and to ground (Figure 25) will shunt damaging currents away from the internal and ESD diodes in the event that the supply is applied to the device before the supply. If positive voltages are applied to the logic or analog video input pins before is applied, current will flow through the internal ESD diodes to the pin. The presence of large decoupling capacitors and the loading effect of other circuits connected to, can result in damaging currents through the ESD diodes and other active circuits within the device. Therefore, adequate current limiting on the digital and analog inputs is needed to prevent damage during the time the voltages on these inputs are more positive than. Limiting the Output urrent No output short circuit current limit exists on these parts. All applications need to limit the output current to less than 5mA. Adequate thermal heat sinking of the parts is also required. FN745 Rev 3. Page of 3 August 6, 22
P Board Layout The frequency response of this circuit depends greatly on the care taken in designing the P board. The following are recommendations to achieve optimum high frequency performance from your P board. The use of low inductance components such as chip resistors and chip capacitors is strongly recommended. Minimize signal trace lengths. Trace inductance and capacitance can easily limit circuit performance. Avoid sharp corners, use rounded corners when possible. Vias in the signal lines add inductance at high frequency and should be avoided. PB traces greater than " begin to exhibit transmission line characteristics with signal rise/fall times of ns or less. High frequency performance may be degraded for traces greater than one inch, unless strip lines are used. Match channel-channel analog I/O trace lengths and layout symmetry. This will minimize propagation delay mismatches. Maximize use of A de-coupled PB layers. All signal I/O lines should be routed over continuous ground planes (i.e., no split planes or PB gaps under these lines). Avoid vias in the signal I/O lines. Use proper value and location of termination resistors. Termination resistors should be as close to the device as possible. When testing use good quality connectors and cables, matching cable types and keeping cable lengths to a minimum. Minimum of 2 power supply de-coupling capacitors are recommended (pf,.µf) as close to the devices as possible. Avoid vias between the cap and the device because vias add unwanted inductance. Larger caps can be farther away. When vias are required in a layout, they should be routed as far away from the device as possible. The NI pins are placed on both sides of the input pins. These pins are not internally connected to the die. It is recommended these pins be tied to ground to minimize crosstalk.
