The MAX9687 is a dual, ultra-fast ECL comparator manufactured with a high-frequency bipolar process (fT = 6GHz) capable of very short propagation delays. This design maintains the excellent DC matching characteristics normally found only in slower comparators.
The MAX9687 is pin-compatible with the AD9687 and Am6687, but exceeds their AC characteristics.
The MAX9687 has differential inputs and complementary outputs that are fully compatible with ECL-logic levels. Output current levels are capable of driving 50½ terminated transmission lines. The ultra-fast operation makes signal processing possible at frequencies in excess of 600MHz.
A latch-enable (LE) function is provided to allow the comparator to be used in a sample/hold or track/hold mode. The latch-enable inputs are designed to be driven from the complementary outputs of a standard ECL gate. When LE is high andLE is low, the comparator functions normally. When LE is forced low and LE is high, the comparator outputs are locked in the logical
states determined by the input conditions at the time of the latch transition. If the latch-enable function is not used on either of the two comparators, the appropriate LE input must be connected to ground; the companion LE input can be left open.
