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.

FEATURES
