MAX9247ECM/V+ is an integrated serializer/deserializer (SerDes) designed for driving high-speed data transmissions over one twisted-pair wire. It offers a full suite of features, plus the ultra-low power, high-speed transmit/receive (TX/RX) performance, and engineering flexibility required for advanced integrated display applications such as eBook displays, automotive graphic Displays and handheld devices. Available in the small 14-Pin TDFN package, the MAX9247ECM/V+ integrates a transmitter, a receiver, system clock synthesis and support for a range of data rates from 6Mbps to 5Gbps. The deserializer Performs clock and data recovery and also interfaces with the system clock.
MAX9247ECM/V+ Application Field:It is mainly applicable to any interface requiring the transmission of high speed serial bus data over a single twisted pair cable. It interfaces to existing LVDS and other HSTL data buses, as well as to GDDR2, GDDR3, LPDDR2 and other memory standards. It can be used for any application that requires transmission of up to 5.0Gbits/sec. It is mainly used for driving advanced integrated display products, such as eBook displays, automotive graphic displays and handheld devices.
MAX9247ECM/V+ Working Principle
MAX9247ECM/V+ transmits data over a single twisted pair cable by encoding and decoding data with a unique coding scheme. The core of the design is the forward error correction (FEC) algorithm, which uses two coding techniques: differential encoding (DE) and interleaving (IL).
- Differential Encoding: Differential encoding is an encoding technique used to increase the robustness of data transmission over channels with high signal-to-noise ratio. It works by differentially encoding two sequences of data so that changes in one signal can be detected and corrected in the other signal. After differential encoding, the signal is buffered through a transmit line driver, which is a logic gate used to increase the amplitude of the signal before it is sent over the line.
- Interleaving:Interleaving is a technique whereby the signal is split into multiple sub-signals which are then transmitted in succession to improve signal-to-noise ratio. The idea is that by breaking the signal into multiple parts and sending them over the wire one at a time, the signal can be received with less noise and interference. This is because the interference will be spread out over multiple transmissions, making it easier to detect and correct.
Data transmission over the line is done using non-return-to-zero (NRZ) modulation. In this method, the signal is modulated using a logic gate, and its output is either a one or a zero, depending on the input data. This allows for a much faster data transmission rate than other modulation methods, as well as for more efficient transmission of data over noisy lines.
Once the signal has been correctly received by the deserializer, it is then buffered and decoded using the same FEC algorithm used for encoding. This ensures that all errors which may have been introduced during transmission are corrected, and that a correct stream of data is sent on to the receiving device.
Conclusion
The MAX9247ECM/V+ is an integrated serializer/deserializer that is designed to transmit high-speed data over single twisted-pair wires. It integrates a transmitter, a receiver, system clock synthesis and support for data rates of up to 5Gbps. It uses differential encoding and interleaving techniques to ensure error-free data transfer, as well as non-return-to-zero (NRZ) modulation for a higher data transfer rate than other modulation methods. Combining these features, the MAX9247ECM/V+ is well suited for the transmission of data over noisy lines, allowing for reliable and fast communication.
