The DS92LV1212AMSAX is a low signal cable serial transceiver that is intended to be used in serial communication systems using multiple low signal differential pairs. It interfaces between the physical medium and logic signaling levels and supports a wide range of uses. It is well suited for use in SAS (Serial Attached SCSI), SAS-2, SATA (Serial ATA), SFF-8431, SFF-8482, SFF-8087, SFF-8498, SFF-8639 and SFF-8680 compliant designs.

The DS92LV1212AMSAX is capable of providing single-ended to differential data conversion, as well as differential to single-ended data conversion. The device features 8-bit bidirectional, differential data through a single-ended 4-bit interface. This interface can be configured as an optical medium via the SFF-8431 and SFF-8482 connector interfaces. It also supports additional interface data rates such as 1.5 Gb/s, 3.0 Gb/s and 6.0 Gb/s.

The DS92LV1212AMSAX is a transceiver with a low signal differential output and input complete with terminations. It provides a 1:2 multiplexer for serializing data which can accommodate multiple low signal (100 mV) differential pairs. This device acts as a deserializer for parallel data receipt. It offers a triangular coding algorithm which allows for increased data rate for longer distance transmission. The device also contains an internal version of the DS92LV1212AM circuit which provides the receiver characteristics and the lower transition voltage needed for the high data rate applications.

The device supports both low to high and high to low LCD convergence data and provides a logic low supply voltage condition when outputting low-to-high data transition. This condition allows for increased energy savings by reducing the current consumption in the system. The internal 8-bit pre-emphasis circuit increases the edge rate of the data thus increasing the maximum data rate of the system.

The DS92LV1212AMSAX integrates the receiver characteristics with a low signal differential output stage. This differential output produces the received data with the output slew rate and offset adjusted by the internal data rate control logic. This integrated circuit also allows a single-ended to differential conversion capabilities for reception, thus increasing the efficiency and flexibility of the system.

The DS92LV1212AMSAX supports both serial and parallel transmission modes. In serial mode, the output device operates in a single-stage mode to simplify the communication interface and reduce the overhead associated with serial transmission. The device also supports two-wire communication, allowing for easy and remote device control. In parallel mode, the output device operates in two-stage mode, allowing for high-digit rate transmission.

The device also offers current pre-charging capabilities which allow the transmitter and receiver to be powered independently. This feature offers improved power management and reduced voltage droop, thus enabling improved transmission reliability and repeatability. The device also allows for automatic link detection, eliminating the manual intervention required in serial communication systems.

The DS92LV1212AMSAX support a wide range of data rates, ranging from 200 Mbps up to 6.0 Gb/s. The device also provides an extended bandwidth of up to 8.5 GHz, allowing for higher data rates and longer distance transmission. The low signal transmission line termination voltage is adjustable, allowing for improved impedance matching and signal transmission over long distances as well as reducing EMI susceptibility.

In summary, the DS92LV1212AMSAX is an ideal device for use in serial communication systems using multiple low signal differential pairs. It is capable of providing both single-ended to differential data conversion, as well as differential to single-ended data conversion. It supports data rates from 200 Mbps to 6.0 Gb/s and provides an extended bandwidth of up to 8.5 GHz. This device is well suited for use in SAS (Serial Attached SCSI), SAS-2, SATA (Serial ATA), SFF-8431, SFF-8482, SFF-8087, SFF-8498, SFF-8639 and SFF-8680 compliant designs.
