TI transmit/receive processors for 3G, 4G wireless base stations provide industry’s widest bandwidth digital pre-distortion

DALLAS Feb. 10, 2011 Mobile World Congress www.ti.com/gc533x-pr

TMS320C6748 floating point DSP

Key features and benefits

  • Provides up to 148 MHz of fifth order corrected DPD bandwidth across two transmitters with CFR 2 dB better than competitive solutions, enabling power amplifier efficiencies as high as 40 percent in three carrier LTE operation with 54-dB adjacent channel leakage ratio (ACLR) and 48-dBm output.
  • Delivers 20 dB of ACLR improvement compared to uncorrected signals in wide-bandwidth applications and 40 dB improvement in narrow-bandwidth applications while offering multi-channel, multi-carrier, multi-mode and multi-band support for standards such as 3GPP, MC-GSM, WiMAX, WiBRO and 3GPP2.
  • Includes interfaces for up to four transmit and eight receive antennas and a real or complex observation path, enabling 2×2, 2×4, 4×4 and 4×8 transmit/receive solutions while simplifying board layout and reducing cost by an order of magnitude compared to FPGAs.
  • Features 48 digital up/down convert channels configurable for data rates as wide as 184 MS/s with four fractional re-samplers, 48-bit NCOs and a bulk up-converter that enables expanded clocking and frequency planning flexibility.  
  • Integrates I/Q imbalance correction for enhanced performance of wideband complex receive and DPD observation signal chains, enabling lower sample rate and lower-cost receive and feedback analog-to-digital converters (ADCs).
