EL5177 ® Data Sheet August 8, 2005 FN7344.3 550MHz Differential Twisted-Pair Driver Features The EL5177 is a high bandwidth amplifier with an output in differential form. It is primarily targeted for applications such as driving twisted-pair lines or any application where common mode injection is likely to occur. The input signal can be in either single-ended or differential form but the output is always in differential form. • Fully differential inputs, outputs, and feedback On the EL5177, two feedback inputs provide the user with the ability to set the device gain (stable at minimum gain of one.) • Differential input range ±2.3V • 550MHz 3dB bandwidth • 1100V/µs slew rate • Low distortion at 20MHz • Single 5V or dual ±5V supplies • 40mA maximum output current The output common mode level is set by the reference pin (REF), which has a -3dB bandwidth of 110MHz. Generally, this pin is grounded but it can be tied to any voltage reference. • Low power - 12.5mA typical supply current Both outputs (OUT+, OUT-) are short circuit protected to withstand temporary overload condition. • Twisted-pair drivers The EL5177 is available in the 10-pin MSOP package and is specified for operation over the full -40°C to +85°C temperature range. • Pb-free plus anneal available (RoHS compliant) Applications • Differential line drivers • VGA over twisted-pair • ADSL/HDSL drivers See also EL5174 (EL5177 in 8-pin MSOP.) • Single ended to differential amplification Ordering Information • Transmission of analog signals in a noisy environment PART NUMBER Pinout PACKAGE TAPE & REEL PKG.

It can be used as single/differential ended to differential converter. The EL5177 is internally compensated for closed loop gain of +1 of greater. Connected in gain of 1 and driving a 1kΩ differential load, the EL5177 has a -3dB bandwidth of 550MHz. Driving a 200Ω differential load at gain of 2, the bandwidth is about 130MHz. The EL5177 is available with a power down feature to reduce the power while the amplifier is disabled. The gain setting for EL5177 is: R F1 + R F2 V ODM = ( V IN + – V IN - ) × 1 + ---------------------------- RG 2R F V ODM = ( V IN + – V IN - ) × 1 + ----------- RG V OCM = V REF Where: RF1 = RF2 = RF RF1 Input, Output, and Supply Voltage Range The EL5177 has been designed to operate with a single supply voltage of 5V to 10V or a split supplies with its total voltage from 5V to 10V. The amplifiers have an input common mode voltage range from -4.3V to 3.4V for ±5V supply. The differential mode input range (DMIR) between the two inputs is from -2.3V to +2.3V. The input voltage range at the REF pin is from -3.3V to 3.7V. If the input common mode or differential mode signal is outside the above-specified ranges, it will cause the output signal distorted. The output of the EL5177 can swing from -3.8V to +3.8V at 1kΩ differential load at ±5V supply. As the load resistance becomes lower, the output swing is reduced. Differential and Common Mode Gain Settings The voltage applied at REF pin can set the output common mode voltage and the gain is one. The differential gain is set by the RF and RG network. 8 FBP VIN+ VINVREF RG VO+ IN+ INREF VO- FBN RF2 FIGURE 23. Choice of Feedback Resistor and Gain Bandwidth Product For applications that require a gain of +1, no feedback resistor is required. Just short the OUT+ pin to FBP pin and OUT- pin to FBN pin. For gains greater than +1, the feedback resistor forms a pole with the parasitic capacitance at the inverting input. As this pole becomes smaller, the amplifier's phase margin is reduced. This causes ringing in the time domain and peaking in the frequency domain. Therefore, RF has some maximum value that should not be exceeded for optimum performance. If a large value of RF FN7344.3 August 8, 2005 EL5177 must be used, a small capacitor in the few Pico farad range in parallel with RF can help to reduce the ringing and peaking at the expense of reducing the bandwidth. The bandwidth of the EL5177 depends on the load and the feedback network. RF and RG appear in parallel with the load for gains other than +1. As this combination gets smaller, the bandwidth falls off. Consequently, RF also has a minimum value that should not be exceeded for optimum bandwidth performance. For gain of +1, RF = 0 is optimum. For the gains other than +1, optimum response is obtained with RF between 500Ω to 1kΩ. The EL5177 has a gain bandwidth product of 200MHz for RLD = 1kΩ. For gains ≥5, its bandwidth can be predicted by the following equation: Gain × BW = 200MHz Driving Capacitive Loads and Cables The EL5177 can drive 23pF differential capacitor in parallel with 1kΩ differential load with less than 5dB of peaking at gain of +1. If less peaking is desired in applications, a small series resistor (usually between 5Ω to 50Ω) can be placed in series with each output to eliminate most peaking. However, this will reduce the gain slightly. If the gain setting is greater than 1, the gain resistor RG can then be chosen to make up for any gain loss which may be created by the additional series resistor at the output. When used as a cable driver, double termination is always recommended for reflection-free performance. For those applications, a back-termination series resistor at the amplifier's output will isolate the amplifier from the cable and allow extensive capacitive drive. However, other applications may have high capacitive loads without a back-termination resistor. Again, a small series resistor at the output can help to reduce peaking. maintained if the output current never exceeds ±40mA. This limit is set by the design of the internal metal interconnect. Power Dissipation With the high output drive capability of the EL5177. It is possible to exceed the 135°C absolute maximum junction temperature under certain load current conditions. Therefore, it is important to calculate the maximum junction temperature for the application to determine if the load conditions or package types need to be modified for the amplifier to remain in the safe operating area. The maximum power dissipation allowed in a package is determined according to: T JMAX – T AMAX PD MAX = --------------------------------------------Θ JA Where: TJMAX = Maximum junction temperature TAMAX = Maximum ambient temperature θJA = 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: ∆V O PD = V S × I SMAX + V S × -----------R LD Where: VS = Total supply voltage ISMAX = Maximum quiescent supply current per channel ∆VO = Maximum differential output voltage of the application RLD = Differential load resistance Disable/Power-Down The EL5177 can be disabled and placed its outputs in a high impedance state. The turn off time is about 1.2µs and the turn on time is about 130ns. When disabled, the amplifier's supply current is reduced to 1.7µA for IS+ and 120µA for IStypically, thereby effectively eliminating the power consumption. The amplifier's power down can be controlled by standard CMOS signal levels at the EN pin. The applied logic signal is relative to VS+ pin. Letting the EN pin float or applying a signal that is less than 1.5V below VS+ will enable the amplifier. The amplifier will be disabled when the signal at EN pin is above VS+ - 0.5V. Output Drive Capability The EL5177 has internal short circuit protection. Its typical short circuit current is ±40mA. If the output is shorted indefinitely, the power dissipation could easily increase such that the part will be destroyed. Maximum reliability is 9 ILOAD = Load current By setting the two PDMAX equations equal to each other, we can solve the output current and RLD to avoid the device overheat. Power Supply Bypassing and Printed Circuit Board Layout As with any high frequency device, a good printed circuit board layout is necessary for optimum performance. Lead lengths should be as sort as possible. The power supply pin must be well bypassed to reduce the risk of oscillation. For normal single supply operation, where the VS- pin is connected to the ground plane, a single 4.7µF tantalum capacitor in parallel with a 0.1µF ceramic capacitor from VS+ to GND will suffice. This same capacitor combination should be placed at each supply pin to ground if split supplies are to FN7344.3 August 8, 2005 EL5177 be used. In this case, the VS- pin becomes the negative supply rail. 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. Minimizing parasitic capacitance at the amplifier's inverting input pin is very important. The feedback resistor should be placed very close to the inverting input pin. Strip line design techniques are recommended for the signal traces.
