TI Announces Availability of New 1-48 Channel Full Featured Digital Up and Down Converter

Texas Instruments (News - Alert) Incorporated (TI) has announced the availability of a new software-defined wideband transmit and receive signal processor, GC6016, which includes digital up and down converter (DUC/DDC), transmit, receive, and capture buffer blocks.

Combining TI's latest generation of low-power, high-speed, high-bandwidth Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs), the new GC6016 DUC/DDC is capable of providing a new level of wide bandwidth signal acquisition and transmission with low power, high density and low cost, according to a press release.

Officials with TI said in the release that the new GC6016 DUC/DDC supports one to 48 DUC/DDC channels across four transmit and eight receive streams with up to 155 million samples per second (MS/s) composite bandwidth at a very affordable price.

Sampling in a 23-mm x 23-mm TE-PBGA package and priced at $64.95 USD in 1,000-unit quantities, the new GC6016 DUC/DDC is ideal for wireless applications, such as narrow and wideband 2G, 3G and 4G wireless base stations and digital repeaters, software defined radios (SDRs), MIMO transceivers and wideband digitizers.

One of the key benefits of new GC6016 DUC/DDC is it features 48 digital up and down convert channels configurable for data rates of 184 MS/s with 98,304 decimation and interpolation range. This feature allows the DUC/DDC to support multiple wide and narrow bandwidth signals with high channel selectivity.

According to TI, the new GC6016 DUC/DDC can provide fractional re-samplers, crest factor reduction, 48-bit numerically controlled oscillators (NCO) as well as automatic gain control (AGC) supporting up to four transmit and eight receive antennas simultaneously with multi-band and multi-mode configurations.

In order to enable 2x2, 2x4, 4x4 and 4x8 a transmit/receive solution, TI has incorporated GC6016 DUC/DDC with interfaces for up to four transmit and eight receive antennas with real or complex inputs. This functionality simplifies board layout and also reduces cost by an order of magnitude compared to FPGAs.

In addition, the new GC6016 DUC/DDC also features 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 DACs and ADCs such as the ADS5400, ADS4149 and DAC3484.

For enhanced performance of wideband complex transmit and receive signal chains, the new GC6016 DUC/DDC integrates I/Q imbalance correction, thereby enabling lower sample rate and lower cost DACs and ADCs for wide bandwidth applications.

Recently, TI also rolled-out its next generation of wireless power technology, bq51013 receiver integrated circuit (IC), TMCnet reported.
