TI's software-defined digital up, down converter drives down cost, boosts channel sensitivity

Supports one to 48 channels, up to four transmit and eight receive antennas

(PresseBox) (Dallas, ) Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's most powerful software-defined digital up and down converter (DUC/DDC). The GC6016 DUC/DDC supports one to 48 channels and up to 155 million samples per second (MS/s) composite bandwidth, with a price point of less than $60 in 1,000-unit quantities. The GC6016 is suitable for wireless applications, such as narrow and wideband 2G, 3G and 4G wireless base stations and digital repeaters, software defined radios, MIMO transceivers and wideband digitizers. TI will demonstrate the GC6016 on a digital repeater platform at Mobile World Congress (Hall 8, Stand 8A84). For more information and to order samples of the GC6016, visit

Key features and benefits

Features 48 digital up and down convert channels configurable for data rates as wide as 184 MS/s with up to a 98,304 decimation and interpolation range for supporting multiple wide and narrow bandwidth signals with high channel selectivity.

Provides fractional re-samplers, 48-bit numerically controlled oscillators (NCO) and automatic gain control (AGC) supporting up to four transmit and eight receive antennas simultaneously with multi-band and multi-mode configurations.

Includes interfaces for up to four transmit and eight receive antennas with real or complex inputs, enabling 2x2, 2x4, 4x4 and 4x8 transmit/receive solutions while simplifying board layout and reducing cost by an order of magnitude compared to FPGAs.

38 receive low voltage differential signaling (LVDS) pairs and 40 transmit LVDS pairs, each supporting up to 1.24 GSPS to provide a direct interface with TI's newest and highest speed digital-to-analog converters (DACs) and analog-to-digital converters (ADCs), such as the ADS5400, ADS4149 and DAC3283.

Integrates I/Q imbalance correction for enhanced performance of wideband complex transmit and receive signal chains, enabling lower sample rate and lower cost DACs and ADCs for wide bandwidth applications.

Tools and support

The GC6016 digital repeater platform 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 feedback CDCE72010 clock synthesizer and jitter cleaner for system clocking TMS320C6748 fixed/floating point DSP

The GC6016 reference design kit is available through TI today for $8,500. Contact your local Product Information Center (PIC) for more information.

A stand-alone GC6016 evaluation module will be available in 2Q 2011 for $3,500. The GC6016EVM will mate directly to more than 75 high speed data converter evaluation modules, such as the ADS6000, ADS5400, ADS4000, DAC3200 and DAC5600 families, for maximum flexibility during evaluation and system prototyping.

Availability and pricing

The GC6016 is available in a 23-mm x 23-mm TE-PBGA package, priced at $59.95 in 1,000-unit quantities.
