Description
General part information
DS64BR111 Series
The DS64BR111 is an extremely low power, high performance dual-channel repeater for serial links with data rates up to 6.4 Gbps. The DS64BR111 pinout is configured as one bidirectional lane (one transmit, one receive channel).
The DS64BR111 features a powerful 4-stage continuous time linear equalizer (CTLE) to provide a boost of up to +25 dB at 3.2 GHz and open an input eye that is completely closed due to inter-symbol interference (ISI) induced by the interconnect mediums such as an FR-4 backplane or AWG-30 cables. The transmitter features a programmable output de-emphasis driver with up to -12 dB and allows amplitude voltage levels to be selected from 700 mVp-p to 1200 mVp-p to suit multiple application scenarios.
The programmable settings can be applied via pin settings, SMBus (I2C) protocol or an external EEPROM. When operating in the EEPROM mode, the configuration information is automatically loaded on power up – This eliminates the need for an external microprocessor or software driver.
