SP8910 (MP) 5GHZ 410 Fixed Modulus Divider
Preliminary Informationminwoo
DS4360 Issue 1.3 September 1999
初级会计学习The SP8910 is one of a range of very high speed low power prescalers for professional applications. The dividing elements are static D type flip flops and therefore allow operation down to DC if the drive signal is a pul waveform with fast ritime. The output stage has internal100 ohm pull up resistors, giving a 0·5V p-p output. If required, an external 100 ohm can be connected in parallel to give a 50 ohm output.
