com ADVANCE INFORMATION DS3647-1·2 SP8690 200MHz410/11 SP8691 200MHz48/9 The SP8690 and SP8691 are low power ECL variable modulus dividers, with both ECL10K and TTL/CMOS compatible outputs.
They divide by the lower division ratio when either of the ECL control inputs, PE1 or PE2, is in the high state and by the higher ratio when both are low (or open circuit).
