WQFN Package
The DS125BR401A is an extremely low-power high-performance repeater/redriver designed to support four lanes carrying high speed interface up to 12 Gbps. The B-Side receivers continuous time linear equalizers (CTLE) provide high frequency boost of up to +24 dB at 6 GHz (12 Gbps) and are capable of opening an input eye that is completely closed due to inter symbol interference (ISI) induced by interconnect medium such as backplane traces or twinaxial copper cables. The programmable equalization allows maximum flexibility in the physical placement within the interconnect channel. The A-Side channel has a 10 dB linear equalizer and linear output driver.
The A-Side channel has a settable 3-10 dB linear equalizer coupled to a linear output driver. When operating in SAS-3 and PCIe Gen-3 applications the DS125BR401A preserves transmit signal characteristics allowing the host controller and the end point to negotiate transmit equalizer coefficients. This transparency to the link training protocol aides system level interoperability and minimum latency.
The programmable settings can be applied easily via Terminals, software (SMBus or I2C), or loaded via an external EEPROM. In EEPROM mode, the configuration information is automatically loaded on power up, which eliminates the need for an external microprocessor or software driver.
