THIS DOCUMENT IS FOR MAINTENANCE PURPOSES ONLY AND IS NOT RECOMMENDED FOR NEW DESIGNS DS 3292 -1 SP8716/8/9 520MHz LOW CURRENT TWO-MODULUS DIVIDERS SP8716 ÷ 40/41, SP8718 ÷ 64/65, SP8719 ÷ 80/81 are 50mW programmable dividers with a maximum specified operating frequency of 520MHz over the temperature range -40 °C to + 85 °C. The signal (clock) inputs are biased internally and require to be capacitor coupled. The output stage is of an unusual low power design featuring dynamic pull-up, and optimised for driving CMOS. The 0 to 1 output edge should be used to give the best loop delay performance.
