This board is designed to demonstrate the LMH7322 Dual Comparator with RSPECL outputs. It will facilitate the evaluation of the LMH7322 in most of the possible configurations. There is one part containing two comparators mounted onto this board. The intention of this board is to demonstrate the conversion of an analog signal to a digital presentation at LVDS levels and to translate this LVDS signal to RSECL levels. The LATCH function can be evaluated using the two switches mounted on the edge of the board. Two test points located between the comparators allows checking the LVDS levels while the output signals are fed to two SMA connectors that feed the signals on a 50? basis to any scope or analyzer. To demonstrate the hysteresis functionality both hysteresis resistors are mounted on header pins, which makes them changeable in a convenient manner. Only two supply voltages are needed to make this setup work. The positive supply is +2.5V and the negative supply is −5.2V.
