Mixed-Signal Front-End (MxFE™) Baseband Transceiver for Broadband Applications

Product Details

The AD9863 is a member of the MxFE family—a group of integrated converters for the communications market. The AD9863 integrates dual 12-bit analog-to-digital converters (ADC) and dual 12-bit digital-to-analog converters (TxDAC®). The AD9863 ADCs are optimized for ADC sampling of 50 MSPS and less. The dual TxDACs operate at speeds up to 200 MHz and include a bypassable 2× or 4× interpolation filter. The AD9863 is optimized for high performance, low power, and small form factor to provide a cost-effective solution for the broadband communications market.

The AD9863 uses a single input clock pin (CLKIN) or two independent clocks for the Tx path and the Rx path. The ADC and TxDAC clocks are generated within a timing generation block that provides user programmable options such as divide circuits, PLL multipliers, and switches.

A flexible, bidirectional 24-bit I/O bus accommodates a variety of custom digital back ends or open market DSPs.

In half-duplex systems, the interface supports 24-bit parallel transfers or 12-bit interleaved transfers. In full-duplex systems, the interface supports a 12-bit interleaved ADC bus and a 12-bit interleaved TxDAC bus. The flexible I/O bus reduces pin count, also reducing the required package size on the AD9863 and the device to which it connects.

The AD9863 can use either mode pins or a serial programmable interface (SPI) to configure the interface bus, operate the ADC in a low power mode, configure the TxDAC interpolation rate, and control ADC and TxDAC power-down. The SPI provides more programmable options for both the TxDAC path (for example, coarse and fine gain control and offset control for channel matching) and the ADC path (for example, the internal duty cycle stabilizer and twos complement data format).

The AD9863 is packaged in a 64-lead LFCSP (low profile, fine pitched, chip scale package). The 64-lead LFCSP footprint is only 9 mm × 9 mm and is less than 0.9 mm high, fitting into such tightly spaced applications as PCMCIA cards.

Product Details

The AD-DAC-FMC-ADP adapter board allows any of Analog Devices' DPG2-compatiable High-Speed DAC Evaluation Boards to be used on a Xilinx® evaluation board with a FMC connector. The adapter board uses the Low Pin Count (LPC) version of the FMC connector, so it can be used on either LPC or HPC hosts (such as the ML605 or SP605).

For a list of compatible evaluation boards, please see the "DPG2" information on our Data Pattern Generator (DPG) High-Speed DAC Evaluation Platform page.
