The AD9208 is a dual, 14-bit, 3 GSPS analog-to-digital converter (ADC). The device has an on-chip buffer and a sample-and-hold circuit designed for low power, small size, and ease of use. This product is designed to support communications applications capable of direct sampling wide bandwidth analog signals of up to 5 GHz. The −3 dB bandwidth of the ADC input is 9 GHz. The AD9208 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage referenceeases design considerations. The analog input and clock signals are differential inputs. The ADC data outputs are internally connected to four digital downconverters (DDCs) through a crossbar mux. Each DDC consists of up to five cascaded signalprocessing stages: a 48-bit frequency translator (numerically controlled oscillator (NCO)), and up to four half-band decimationfilters. The NCO has the option to select preset bands over the general-purpose input/output (GPIO) pins, which enables the selection of up to three bands. Operation of the AD9208 between the DDC modes is selectable via SPI-programmable profiles.In addition to the DDC blocks, the AD9208 has several functions that simplify the automatic gain control (AGC) function in acommunications receiver. The programmable threshold detector allows monitoring of the incoming signal power using the fast detect control bits in Register 0x0245 of the ADC. If the input signal level exceeds the programmable threshold, the fast detect indicator goes high. Because this threshold indicator has low latency, the user can quickly turn down the system gain to avoidan overrange condition at the ADC input. In addition to the fast detect outputs, the AD9208 also offers signal monitoring capability. The signal monitoring block provides additional information about the signal being digitized by the ADC.The user can configure the Subclasss 1 JESD204B-based high speed serialized output in a variety of one-lane, two-lane, four-lane, and eight-lane configurations, depending on the DDC configuration and the acceptable lane rate of the receiving logic device. Multidevice synchronization is supported through the SYSREF± and SYNCINB± input pins.The AD9208 has flexible power-down options that allow significant power savings when desired. All of these features canbe programmed using a 3-wire serial port interface (SPI).The AD9208 is available in a Pb-free, 196-ball BGA, specified over the −40°C to +85°C ambient temperature range.
