Introduction

The CYW15G0403DXB-BGI is a high-speed, high-end Gigabit Ethernet transceiver device produced by Silicon Motion Inc. It integrates an integrated system-on-chip (SoC), voltage regulator and transmitter/receiver set into a compact package making it suitable for small form factor network applications. It supports essential Ethernet protocols IEEE 802.3ab 101001000 and 1000BASE-T. It uses differential data signaling, so it has low noise, low power consumption and low radiation interference due to the reduced waveform size on the transmission line.

Application Field

The CYW15G0403DXB-BGI is suitable for applications with security,reliability and wide bandwidth requirements, such as fiber optic and copper cable networks, broadband access networks, enterprise networks, and many media streaming applications. It is mainly used as a physical layer transceiver in applications like switches, gateways, routers, access points and bridge. It also supports both full-duplex and half-duplex communication and interaction.

Working Principle

The CYW15G0403DXB-BGI is an integrated solution with an SoC and a transceiver. The transmitter of the transceiver is used to convert data bits into signals and then these signals move to the medium via an RJ45 connector.The transmitter performs coding, scrambling, serialization and emission of the transmitted symbols onto the physical channel. At the receiver side, signals from the physical channel are received and converted into the bit stream. The receiver performs de-scrambling, decoding, parallelization and synchronizing of the received data.The device also consists of a voltage regulator that provides the required level of power for the transceiver. The regulator provides 3.3V and 1.2V to the device. The device also consists of a pre-emphasis filter, a loop filter and an equalizer. The pre-emphasis filter offers additional noise immunity. The loop filter is used to reduce frequency response error by reducing beats caused by modulation. The equalizer is used to ensure optimum performance.

Conclusion

The CYW15G0403DXB-BGI is a compact and cost-effective single-chip gigabit Ethernet transceiver device produced by Silicon Motion Inc. which integrates an SoC, voltage regulator, and transmitter/receiver set into the package. The device is mainly used in the applications where reliability, security and wide bandwidth is required. It has low noise, low power consumption and low interference. The device consists of pre-emphasis filter, loop filter and equalizer for optimum performance.
