Description
General part information
DS100BR111A Series
The DS100BR111 is an extremely low power, high performance repeater designed to support serial links with data rates up to 10.3 Gbps. The DS100BR111 pinout is configured as one bidirectional lane (one transmit, one receive channel). The DS100BR111 inputs feature a powerful 4-stage continuous time linear equalizer (CTLE) to provide a boost of up to +36 dB at 5 GHz and open an input eye that is completely closed due to inter-symbol interference (ISI) induced by the interconnect mediums such as board traces or twin-axial copper cables. The transmitter features a programmable output de-emphasis driver with up to –12 dB and can drive output voltage levels from 700 mVp-p to 1300 mVp-p.
When configured as a 10G-KR repeater, the DS100BR111 allows the KR host and the end point to optimize the full link by adjusting transmit and receive equalizer coefficients using back-channel communication techniques specified by the 802.3ap Ethernet standard.
The programmable settings can be applied via pin control, SMBus protocol, or an external EEPROM. In the EEPROM mode, the configuration information is automatically loaded on power up, thereby eliminating the need for an external microprocessor or software driver.
