SP5611

1·3GHz Bidirectional I²C Bus Controlled Synthesiser

Advance Information

Supersedes February 1997 version, DS3758-4.1

DS3758 - 5.0 June 1998

The SP5611 is a single chip frequency synthesiser de-

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

standard I²C BUS format. The device contains 4 addressable

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

The information on these ports can be read via the I²C BUS.

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.
