Ultra Low Power 10.3 Gbps 2-Channel Repeater with Input Equalization and Output De-Emphasis General Description The DS100BR111 is an extremely low power, high performance dual-channel repeater for 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 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. 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 standard. The programmable settings can be applied via pin contol, 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. Part of National's PowerWise family of energy efficient devices, the DS100BR111 consumes just 65 mW/channel (typical), and allow the option to turn-off unused channels. This ultra low power consumption eliminates the need for external heat sinks and simplifies thermal management in active cable applications. Notice: This document is not a full datasheet.
