PRODUCTION DATA.
The DS280BR810 is an eight-channel multi-rate linear repeater with integrated signal conditioning. The eight channels operate independently from one another. Each channel includes a continuous-time linear equalizer (CTLE), an optional FIR filter and a linear output driver, which compensate for the presence of a dispersive transmission channel between the source transmitter and the final receiver.
All transmit and receive channels on the DS280BR810 are AC-coupled with physical AC coupling capacitors (220 nF ±20%) on the package substrate. This ensures common mode voltage compatibility with all link partners and eliminates the need for AC coupling capacitors on the system PCB, thereby saving cost and greatly reducing PCB routing complexity.
The DS280BR810 is configurable through a single SMBus port. The DS280BR810 can also act as an SMBus master to configure itself from an EEPROM.
The sections which follow describe the functionality of various circuits and features within the DS280BR810. For more information about how to program or operate these features, consult the DS280BR810 Programming Guide.
