3 / 32 page  AD6672 Rev. 0 | Page 3 of 32 When the NSR block is disabled, the ADC data is provided directly to the output at a resolution of 11 bits. This allows the AD6672 to be used in telecommunication applications, such as a digital predistortion observation path, where wider bandwidths are required. After digital signal processing, multiplexed output data is routed into one 11-bit output port such that the maximum data rate is 500 Mbps (DDR). This output is LVDS and supports ANSI-644 levels. The AD6672 receiver digitizes a wide spectrum of IF frequencies. This IF sampling architecture greatly reduces component cost and complexity compared with traditional analog techniques or less integrated digital methods. Flexible power-down options allow significant power savings. Programming for device setup and control is accomplished using a 3-wire, SPI-compatible serial interface with numerous modes to support board level system testing. The AD6672 is available in a 32-lead, RoHS-compliant LFCSP and is specified over the industrial temperature range of −40°C to +85°C. This product is protected by a U.S. patent. PRODUCT HIGHLIGHTS 1. Integrated 11-bit, 250 MSPS ADC with a noise shaping requantizer option. 2. Operation from a single 1.8 V supply and a separate digital output driver supply accommodating LVDS outputs. 3. On-chip 1-to-8 integer clock divider function to support a wide range of clocking. 4. Noise shaping requantizer function allows attaining improved SNR within a reduced frequency band. With NSR enabled, the AD6672 supports up to 82 MHz at 250 MSPS. 5. Standard serial port interface (SPI) that supports various product features and functions, such as data formatting (offset binary, twos complement, or gray coding), enabling the clock DCS, power-down, test modes, and voltage reference mode. |
