• C ommon mode range –3.0 to +8.0 V Low input bias current <100 pA Propagation delay 1.5 ns (max) Low offset ±25 mV Low feedthrough and crosstalk Differential latch control APPLICA TIONS Automated test equipment H igh-speed instrumentation Window comparators High-speed timing Line receivers High-speed triggers Threshold detection Peak detection GENERAL DESCRIPTION The SPT9693 is a high-speed, wide common mode volt- age, JFET input, dual comparator. It is designed for appli- cations that measure critical timing parameters in which wide common mode input voltages of –3.0 to +8.0 V are required. Propagation delays are constant for overdrives greater than 50 mV. JFET inputs reduce the input bias currents to the nanoamp level, eliminating the need for input drivers and buffers in most applications. The device has differential analog inputs and complementary logic outputs com- patible with ECL systems. Each comparator has a complementary latch enable control that can be driven by standard ECL logic. The SPT9693 is available in 20-contact LCC and 20-lead PLCC packages over the commercial temperature range. It is also available in die form . BLOCK DIA GRAM

The SPT9693 is an ultrahigh-speed dual voltage com- parator. It offers tight absolute characteristics. The device has differential analog inputs and complementary logic outputs compatible with ECL systems. The output stage is adequate for driving terminated 50 ohm transmission lines. The SPT9693 has a complementary latch enable control for each comparator. Both should be driven by standard ECL logic levels. A common mode voltage range of –3 V to +8 V is achieved by a proprietary JFET input design, which requires a separate negative power supply (AV EE ). The dual comparators have separate AVCC , AVEE , and grounds for each comparator to achieve high crosstalk rejection. Single-channel operation can be accomplished by floating all pins (including the ground and supply pins) of the un- used comparator. Power dissipation during single-channel operation is 50% of the dissipation during dual-channel operation. This comparator offers the following improvements over existing devices:  Ultra low input bias current and input current offset  Common mode voltage of –3 to +8 V  Short propagation delays  Excellent input and output rejection between comparator channels  Improved input protection reliability due to JFET input stage design All of these combined features produce high-performance products with timing stability and repeatability for large system precision.

The typical interface circuit using the comparator is shown in figure 2. Although it needs few external components and is easy to apply, there are several conditions that should be noted to achieve optimal performance. The very high operating speeds of the comparator require careful layout, decoupling of supplies, and proper design of trans- mission lines. Since the SPT9693 comparator is a very high-frequency and high-gain device, certain layout rules must be followed to avoid oscillations. The comparator should be soldered to the board with component lead lengths kept as short as possible. A ground plane should be used, while the input impedance to the part is kept as low as possible, to de- crease parasitic feedback. If the output board traces are longer than approximately half an inch, microstripline techniques must be employed to prevent ringing on the output waveform. Also, the microstriplines must be termi- nated at the far end with the characteristic impedance of the line to prevent reflections. All supply voltages should be decoupled with high-frequency capacitors as close to the device as possible. If using the SPT9693 as a single comparator, the outputs of the inactive comparator can be grounded, left open or terminated with 50 ohms to –2 V. All outputs on the active comparator, whether used or un- used, should have identical terminations to minimize ground current switching transients. All ground pins should be connected to the same ground plane to further improve noise immunity and shielding. Unused outputs must be terminated with 50 ohms to ground.

If LE is high and LE low in the SPT9693, the comparator tracks the input difference voltage. When LE is driven low and LE high, the comparator outputs are latched into their existing logic states. The leading edge of the input signal (which consists of a 150 mV overdrive voltage) changes the comparator out- put after a time of t pdL or tpdH (Q or Q). The input signal must be maintained for a time tS (set-up time) before the LE falling edge and LE rising edge and held for time tH after the falling edge for the comparator to accept data. After t H , the output ignores the input status until the latch is strobed again. A minimum latch pulse width of tpL is needed for strobe operation, and the output transitions occur after a time of t pLOH or tpLOL . The set-up and hold times are a measure of the time required for an input signal to propagate through the first stage of the comparator to reach the latching circuitry. Input signals occurring before t S will be detected and held; those occurring after tH will not be detected. Changes between tS and tH may not be detected. Figure 4 – Timing Diagram SWITCHING TERMS (Refer to figure 4) tpdH INPUT TO OUTPUT HIGH DELAY – The propaga- tion delay measured from the time the input signal reaches the reference voltage (± the input offset voltage) to the 50% point of an output LOW to HIGH transition. t pdL INPUT TO OUTPUT LOW DELAY – The propaga- tion delay measured from the time the input signal reaches the reference voltage (± the input offset voltage) to the 50% point of an output HIGH to LOW transition. t pLOH LATCH ENABLE TO OUTPUT HIGH DELAY – The propagation delay measured from the 50% point of the Latch Enable signal LOW to HIGH transition to 50% point of an output LOW to HIGH transition. t pLOL LATCH ENABLE TO OUTPUT LOW DELAY – The propagation delay measured from the 50% point of the Latch Enable signal LOW to HIGH transition to the 50% point of an output HIGH to LOW transition. t H MINIMUM HOLD TIME – The minimum time after the negative transition of the Latch Enable signal that the input signal must remain unchanged in order to be acquired and held at the outputs. t pL MINIMUM LATCH ENABLE PULSE WIDTH – The minimum time that the Latch Enable signal must be HIGH in order to acquire an input signal change. t S MINIMUM SET -UP TIME – The minimum time before the negative transition of the Latch Enable signal that an input signal change must be present in order to be acquired and held at the outputs. V OD VOLTAGE OVERDRIVE – The difference between the differential input and reference input voltages.
