SP8400
Very Low Phase Noise Synthesiser Divider
The SP8400 is a very low phase noise programmable
divider which is based on a divide by 8/9 dual modulus
prescaler and a 12 stage control counter. This gives a minimum
division ratio of 56 (64 for fractional - N synthesis applications),
and a maximum division ratio of 4103. Special circuit
techniques have been used to reduce the phase noise
considerably below that produced by standard dividers.The
data inputs are CMOS or TTL compatible.
The SP8400 is packaged in a 28 pin plastic SO package.
