SP8716/8/9
520MHz LOW CURRENT TWO-MODULUS DIVIDERS
DS 3292 -1
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.
