PRODUCTION DATA
The TDP2044 is a four-channel multi-rate linear repeater with integrated signal conditioning. The signal channels of the device operate independently from one another. Each channel includes a continuous-time linear equalizer (CTLE) and a linear output driver, which together compensate for a lossy transmission channel between the source transmitter and the final receiver. The linearity of the data path is specifically designed to preserve any transmit equalization while keeping receiver equalization effective.
The TDP2044 can be configured three different ways:
Pin mode – device control configuration is done solely by strap pins. Pin mode is expected to be satisfactory `for many system implementation needs.
SMBus/I2C Primary mode – device control configuration is read from external EEPROM. When the TDP2044 has finished reading from the EEPROM successfully, the device drives the DONEn pin LOW. SMBus/I2C secondary operation is available in this mode before, during, or after EEPROM reading. Note: during EEPROM reading, if the external SMBus/I2C primary wants to access TDP2044 registers, the external controller must support arbitration. The mode is preferred when software implementation is not desired.
SMBus/I2C Secondary mode – provides most flexibility. Requires a SMBus/I2C primary device to configure TDP2044 though writing to the secondary address.
