SP5511 Datasheet (Zarlink Semiconductor) - Bidirectional I2C Bus 4-Address Synthesiser

SP5511, Bidirectional I2C Bus 4-Address 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

SP5511 Bidirectional I2C Bus 4-Address Synthesiser DS3090 - 4.0 January 1997 The SP5511 is a single-chip frequency synthesiser designed for TV tuning systems.

Control data is entered in the standard I2C BUS format.

In 18-lead plastic DIL package, the SP5511 has three addressable current-limited output ports (P0-P3) and four bi-directional output ports (P0-P2) and four addressable bi-directional open-collector ports (P4-P7) of which P6 is also a 3-bit 5-level ADC input.
