The DS110DF111 includes an input – DS110DF111 with DFE : 8.5 to 11.3G Continuous-Time Linear Equalizer (CTLE), clock and data recovery (CDR) and transmit driver on each • Adaptive CTLE up to 34 dB Boost at 11.3G channel. • Self Tuning 5-Tap DFE The DS110DF111 with its on-chip Decision Feedback • Raw Equalized and Retimed Data Loopback Equalizer (DFE) can enhance the reach and • Adjustable Transmit VOD: 600 to 1300 mVp-p robustness of long, lossy, cross-talk-impaired high • Settable Tx De-Emphasis Driver 0 to -12dB speed serial links to achieve BER < 1x10-15. For Less demanding applications/interconnects, the DFE can • Low Power Consumption: 200mW/Channel be switched off and achieve the same BER • Locks to Half/Quarter/Eighth Data Rates for performance. The DS125 and DS110 devices are pin- Legacy Support compatible. • On-Chip Eye Monitor (EOM), PRBS Generator Each channel of the DS110DF111 independently • Input Signal Detection, CDR Lock locks to serial data at data rates from 8.5 to 11.3 Detection/Indicator Gbps or to any supported sub-rate of these data rates. This simplifies system design and lowers • Single 3.3V or 2.5V ±5% Power Supply overall cost. • SMBus, EEPROM, or Pin Based Configuration Programmable transmit de-emphasis driver offers • 4 mm x 4 mm, 24-Pin QFN Package precise settings to meet the SFF-8431 template. The • Operating Temp Range: -40°C to 85°C fully adaptive receive equalization (CTLE and DFE) enables longer distance transmission in lossy copper interconnect and backplanes with multiple connectors. The CDR function is ideal for use in front port parallel optical module applications to reset the jitter budget and retime high speed serial data. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
