DALLAS, Feb. 10, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced the industry's
widest bandwidth, fully-integrated transmit/receive processors with
digital pre-distortion (DPD) for 3G and 4G wireless base stations,
remote radio heads and government communication systems. The GC533x
family features two turn-key processors that provide a complete and
highly flexible digital transmit and receive solution for
wide-bandwidth and multi-antenna wireless base stations at a
fraction of the cost of high-gate-count FPGAs and without the time
and investment required to develop a custom ASIC solution. A
complete system evaluation and reference design kit, which TI will
showcase at Mobile World Congress (Hall 8, Stand 8A84), is also
available. For more information and to order samples of the GC533x
family, visit www.ti.com/gc533x-pr.
The GC533x family provides up to 148 MHz of fifth order
corrected transmit bandwidth with crest factor reduction (CFR),
along with wideband digital up/down converters with fractional
re-samplers, 48-bit numerically controlled oscillators (NCO) and
automatic gain control that can support four transmit and eight
receive antennas simultaneously. When combined with the low-cost,
high-performance TMS320C6748 floating point DSP, the GC533x
platform offers customers a high-performance adaptive DPD algorithm
or the ability to implement their own DPD IP.
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 2x2, 2x4,
4x4 and 4x8 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).
Tools and support
The GC5330SEK system evaluation and reference design kit
provides a complete transceiver reference design for wide bandwidth
applications. It includes the following:
- DAC3283 communications DAC (digital-to-analog converter),
TRF372017 IQ modulator with integrated PLL/VCO and TRF370417 IQ
modulator for diversity transmit
- PGA870 programmable-gain amplifier, THS770006
fully-differential op amp and ADS62P49 ADC for diversity
receive
- PGA870 and ADS41B49 ADC for DPD observation
- CDCE72010 clock synthesizer and jitter cleaner for system
clocking
- TMS320C6748 fixed/floating point DSP
The GC5330SEK is available through TI today for $8500. Software licensing agreement and support
fees may apply. Contact your local Product Information Center (PIC)
for more information.
Availability and pricing
The GC533x family is offered in a 23-mm x 23-mm TE-PBGA
package.
The GC5330, featuring 620 MHz of total DPD bandwidth with up to
four transmit and eight receive antenna support, is available today
for a suggested resale price of $80
in 1000-unit quantities.
The GC5337, offering 740 MHz of total DPD bandwidth with up to
four transmit and eight receive antenna support, will be available
in March for a suggested resale price of $95 in 1,000-unit quantities.
