The HOTLink II™ family of physical layer (PHY) devices is a point-to-point or point-to-multipoint communications building block that provides serialization, deserialization, optional 8B/10B encoding/decoding and framing functions. The quad independent channel device is a member of this frequency agile family that can support serial data rates between 195 and 1.5 Gbps per channel. Within this device, all four channels can simultaneously operate at different data rates and transmit different types of data. To provide this flexible feature, each channel has its own transmit and receive phase-locked loops (PLLs).
