Ultra-fast Ecl-output Comparator

The MAX9690 is an ultra-fast ECL Comparator manufac- tured with a high-frequency bipolar process (fT = 6GHz) capable of very short propagation delays. This design maintains the excellent DC matching characteristics nor- mally found only in slower Comparators The MAX9690 is similar in function to the MAX9685 except the latch- enable input is eliminated. The MAX9690 is pin-compatible with the CMP-08 but exceeds the AC characteristics of that device. The MAX9690 has differential inputs and complemen- tary outputs that are fully compatible with ECL-logic lev- els. Output current levels are capable of driving 50 terminated transmission lines. The ultra-fast operation makes signal processing possible at frequencies in excess of 600MHz By Maxim Integrated Products
