SP5655
2·7GHz Bidirectional I²C Bus Controlled Synthesiser
Advance Information
Supersedes July 1996 version, DS3743-4.3
DS3743 - 5.0 June 1998
The SP5655 is a single chip frequency synthesiser designed
for TV tuning systems. Control data is entered in the standard
I²C BUS format. The device contains 2 addressable current
limited outputs and 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 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 two or more synthesisers
to be used in a system.
