Overview

SP8680B 575MHz410/11 ADVANCE INFORMATION DS3645-1·2 The SP8680B is an ECL variable modulus divider, with ECL and TTL compatible outputs.

The circuit can operate from either ECL or TTL supplies.

It divides by 10 when either of the ECL control inputs, PE1 or PE2, is in the high state and by 11 when both are low (or open circuit).
