2.6GHz Bidirectional I2C BUS Controlled Synthesiser
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 Programmable via I2C BUS Low power consumption (5V 65mA) Low Radiation Phase Lock Detector Varactor Drive Amp Disable 6 Controllable Outputs, 4 Bi-Directional 5 Level ADC Variable I2C BUS Address For Multi Tuner Applications Full ESD Protection* * Normal ESD handling procedures should be observed.APPLICATIONS Satellite TV High IF Cable Tuning Systems
