SP5512, 1.3GHz Bidirectional I2C BUS Controlled Synthesiser

WRITE MODE (FREQUENCY SYNTHESIS) When the device is in the write mode Bytes 213 select the synthesised frequency while Bytes 415 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 that b

SP5512 1.3GHz Bidirectional I2C BUS Controlled Synthesiser Supersedes version in April 1994 Consumer IC Handbook, HB3120 - 2.0 DS2384 - 4.0 January 1997 The SP5512 is a single-chip frequency synthesiser designed for TV tuning systems.

Control data is entered in the standard I2C BUS format.

The device has six controllable open-collector output ports (P2-P7), each capable of sinking 20mA.

In addition, P6 is a 3-bit 5-level ADC input.

The information on these ports can be read via the I2C BUS.
