The SP5611 is a single chip frequency synthesiser de-

signed for TV tuning systems. Control data is entered in the

bidirectional open collector ports, one of which is a 3-bit ADC.

the device has 4 programmable addresses, programmed by

applying a specific input voltage to the P3 address select

input. This enables two or more synthesisers to be used in a

system.

FEATURES

(1) Normal ESD handling precautions should be observed.

(2) The SP5511S does not have a switchable reference

division ratio.
