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.
