Ultra-Fast ECL-Output Comparator
_______________General Description
The MAX9690 is an ultra-fast ECL comparator manufac-
tured with a high-frequency bipolar process (f_T = 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 50Ω
terminated transmission lines. The ultra-fast operation
makes signal processing possible at frequencies in
excess of 600MHz.
