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.

FEATURES

■ Complete 2.6GHz Single Chip System
