... The SP8647 is an ECL variable modulus divider, with ECL10K and TTL/CMOS compatible outputs. It divides by 10 when either of the ECL control inputs, PE1 or PE2 the high state and by 11 when both are low (or open circuit). The two clock inputs are interchangeable and either will act as a clock inhibit when connected to an ECL high level ...
