SP5055
2.6GHz Bidirectional I²C BUS Controlled Synthesiser
Supersedes version in April 1994 Consumer IC Handbook, HB3120 - 2.0
DS2384 - 4.4 May 1996
The SP5055 is a single chip frequency synthesiser designed
for TV tuning systems. Control data is entered in the standard
I²C BUS format. The device contains 4 addressable current
limited outputs and 4 addressable Bi-Directional 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 one fixed
I²C BUS address and 3 programmable addresses, programmed
by applying a specific input voltage to one of the current limited
outputs. This enables 2 or more synthesisers to be used in a
system.
