3 / 4 page Dual, Ultra-Fast ECL-Output Comparator _______________________________________________________________________________________ 3 Note 2: Not tested, guaranteed by design. Note 3: VIN = 100mV, VOD = 10mV. Figure 2. As a high-speed receiver, the MAX9687 is capable of processing signals in excess of 600MHz. Figure 2 is a 100MHz example with an input signal level of 14mVRMS. Figure 1. High-speed receiver application with 50 Ω input and out- put termination. With this configuration, in which a ground plane and microstrip PC board was used, the minimum slew rate for clean out- put switching is 1.6V/µs. For sine-wave inputs, this implies a mini- mum signal size of 360mVRMS at 500MHz and 90mV at 2MHz. 0V -0.9V -1.7V OUTPUT INPUT OUTPUT 500mV/div INPUT 20mV/div 2ns/div VIN -2V 50 Ω Cf Rf 50 Ω 50 Ω 50 Ω LE SWITCHING CHARACTERISTICS (VS = ±5V, TA = +25°C, unless otherwise noted.) 1.4 1.9 PARAMETER SYMBOL MAX9687C/E MIN TYP MAX UNITS TA = +25°C CONDITIONS E RMS = Slew Rate 2f 2 π TA = 0°C to +70°C 1.6 2.2 1.4 1.9 MAX9687M MIN TYP MAX 1.4 1.9 1.7 2.6 TA = +25°C 1.4 1.9 Input to Output High (Notes 2, 3) tpd+ ns TA = -55°C to +125°C 1.9 2.6 Input to Output Low (Notes 2, 3) 1.3 1.8 TA = 0°C to +70°C tpd- 1.4 2.0 1.3 1.8 TA = -55°C to +125°C ns TA = +25°C 1.6 2.2 TA = 0°C to +70°C 1.3 1.8 1.5 2.0 1.7 2.6 Latch-Enable to Output Low (Notes 2, 3) tpd-(E) TA = -55°C to +125°C ns 1.6 1.9 TA = +25°C 1.4 1.8 TA = 0°C to +70°C Latch-Enable to Output High (Notes 2, 3) tpd+(E) ns TA = -55°C to +125°C 3.0 2.0 Latch-Enable Pulse Width (Note 2) 0.5 1.0 tpw(E) Minimum Setup Time ts 0.5 1.0 3.0 2.0 0.5 1.0 Minimum Hold Time th 0.5 1.0 ns __________Applications Information Layout Because of the MAX9687’s large gain-bandwidth charac- teristic, special precautions need to be taken if its high- speed capabilities are to be used. A PC board with a ground plane is mandatory. Mount all decoupling capaci- tors as close to the power-supply pins as possible, and process the ECL outputs in microstrip fashion, consistent with the load termination of 50 Ω to 120Ω. For low-imped- ance applications, microstrip layout at the input may also be helpful. Pay close attention to the bandwidth of the decoupling and terminating components. Chip compo- nents can be used to minimize lead inductance. Input Slew-Rate Requirement As with all high-speed comparators, the high gain- bandwidth product of these devices creates oscillation problems when the input traverses through the linear region. For clean switching without oscillation or steps in the output waveform, the input must meet certain |
