MAX9685
Description
The MAX9685 is an ultra-fast ECL parator manufactured with a high-frequency bipolar process (f T = 6GHz) capable of very short propagation delays. This design maintains the excellent DC matching characteristics normally found only in slower parators. The device is pin-patible with the AD9685 and Am6685, but exceeds their AC characteristics. The MAX9685 has differential inputs and plementary outputs that are fully patible with ECL-logic levels. Output current levels are capable of driving 50Ω 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 parator to be used in a sample-hold mode. When LE is ECL high, the parator functions normally. When LE is driven ECL low, the outputs are forced to an unambiguous ECL-logic state, dependent on the input conditions at the time of the latch input transition. If the latch-enable function is not used, the LE pin...
