Dual, Ultra-fast Ecl-output Comparator

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 char- acteristics 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 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
