The equalizer operates over a range of data rates from 150 Mbps to 3.125 Gbps and automatically adapts to equalize signals sent over any cable length from zero meters to lengths that attenuate the signal by 50 dB at 1.5 GHz. 1 2 • • • • Automatic Equalization of Coaxial and Twisted Pair Cables Data Rates from 150 Mbps to 3.125 Gbps Supports SD and HD Video Resolutions Power Consumption: 115 mW Typical Industrial Temperature Range: -40°C to +85°C The DS30EA101 allows either single-ended or differential input. This enables equalization of signals over coaxial cables as well as twisted pair cables. APPLICATIONS • • • Cable Extension Data Recovery Equalization Security and Surveillance Additional features include an LOS detect and output enable which, when tied together, disable the output when no input signal is present. The DS30EA101 is powered from a single 2.5V supply and consumes 115 mW (typical). It operates over the full industrial temperature range of -40°C to +85°C and is available in a 4 x 4 mm 16-pin WQFN package. 150 Mbps to 3.125 Gbps 100: Differential Cable or 75: Coaxial Cable DS30BA101 DS30EA101 Max Cable Loss ~ 50 dB @ 1.5 GHz Deserializer Serializer Typical Application 1 2 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.

It automatically adjusts its gain to reverse the effects of the cable loss and restore the original signal. For proper operation, the launch amplitude of the signal going into the cable (the signal amplitude prior to the cable attenuation) must be set appropriately. If the signal is single-ended, its single-ended amplitude must be 800 mVP-P ±10%. If the signal is differential, its differential amplitude must be 800 mVP-P ±10% (400 mVP-P single-ended). INPUT INTERFACING The DS30EA101 accepts either differential or single-ended input. The input must be AC coupled. Figure 3 and Figure 4 show the typical configurations for differential input and single-ended input, respectively. For singleended input, the unused input must be properly terminated as shown. OUTPUT INTERFACING The DS30EA101 output signals (OUT+ and OUT- ) are internally terminated 100Ω LVDS outputs. These outputs can be DC coupled to most common differential receivers. LOS AND EN LOS indicates the loss of signal at the DS30EA101 input. LOS is high when no input signal is present and low when a valid input signal is detected. EN can be used to manually disable or enable the OUT+ and OUT- output signals. Applying a high input to EN will disable the DS30EA101 outputs by forcing the output to a logic 1, and applying a low input to EN will force the outputs to be active. EN has an internal pulldown to enable the outputs by default. LOS and EN may be tied together to automatically disable the DS30EA101 outputs when no input signal is present. APPLICATION INFORMATION CABLE EXTENDER APPLICATION The DS30EA101 together with the DS30BA101 form a cable extender chipset optimized for extending serial data streams from serializer/deseralizer (SerDes) pairs and FPGAs over 100Ω differential cables and 75Ω coaxial cables. Setting the correct DS30BA101 output amplitude and proper cable termination are essential for optimal operation. Figure 3 shows the recommended chipset configuration for 100Ω differential cable and Figure 4 shows the recommended chipset configuration for 75Ω coaxial cable.
