FIN12AC Low-Voltage 12-Bit Bi-Directional Serializer/Deserializer with Multiple Frequency Ranges April 2008 FIN12AC Low-Voltage 12-Bit Bi-Directional Serializer/Deserializer with Multiple Frequency Ranges • Low power consumption • Fairchild proprietary low-power CTL interface • LVCMOS parallel I/O interface: 2mA source / sink current Over-voltage tolerant control signals • Parallel I/O power supply VDDP range between 1.65V and 3.6V • Analog power supply range of 2.5V to 3.3V • Multi-mode operation allows for a single device to operate as Serializer or Deserializer • Internal PLL with no external components • Standby power-down mode support • Small footprint packaging 32-terminal MLP and 42-ball BGA • Built-in differential termination • Supports external CKREF frequencies 5MHz to 40MHz • Serialized data rate up to 560Mb/s • Voltage translation from 1.65V to 3.6V • Microcontroller or pixel interfaces • Image sensors • Small displays LCD, cell phone, digital camera, portable gaming, printer, PDA, video camera, automotive The FIN12AC is a 12-bit serializer / deserializer capable of running a parallel frequency range between 5MHz and 40MHz, selected by the S1 and S2 control signals. The bi-directional data flow is controlled through use of a direction DIRI control pin. The devices can be configured to operate in a unidirectional mode only by hardwiring the DIRI pin. An internal Phase-Locked Loop PLL generates the required bit clock frequency for transfer across the serial link. Options exist for dual or single PLL operation, dependent upon system operational parameters. The device has been designed for low power operation and utilizes Fairchild proprietary low-power control Current Transistor Logic CTL interface. The device also supports an ultra low power-down mode for conserving power in battery-operated applications.
