SP5055 2.6GHz Bidirectional I2C BUS Controlled Synthesiser

WRITE MODE (FREQUENCY SYNTHESIS) When the device is in the write mode Bytes 2 + 3 select the synthesised frequency while bytes 4 + 5 select the output port states and charge pump information. Once the correct address is received and acknowledged, the first Bit of the next Byte determines whether th.

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 .
