Product Details

The AD9094 is a quad, 8-bit, 1 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 device is designed for sampling wide bandwidth analog signals of up to 1.4 GHz. The AD9094 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.

The quad 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 reference eases design considerations.

The analog inputs and clock signals are differential inputs. Each pair of ADC data outputs is internally connected to two DDCs through a crossbar mux. Each DDC consists of up to five cascaded signal processing stages: a 48-bit frequency translator, NCO, and up to four half-band decimation filters.

In addition to the DDC blocks, the AD9094 has several functions that simplify the automatic gain control (AGC) function in the communications receiver. The programmable threshold detector allows monitoring of the incoming signal power using the fast detect output bits 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 avoid an overrange condition at the ADC input.

Users can configure each pair of intermediate frequency (IF) receiver outputs onto either one or two lanes of Subclass 1 JESD204B-based high speed serialized outputs, depending on the decimation ratio and the acceptable lane rate of the receiving logic device. Multiple device synchronization is supported through the SYSREF±, SYNCINB±AB, and SYNCINB±CD input pins.

The AD9094 has flexible power-down options that allow significant power savings when desired. All of these features can be programmed using the 1.8 V capable, 3-wire SPI.

The AD9094 is available in a Pb-free, 72-lead LFCSP and is specified over the −40°C to +105°C junction temperature range. This product may be protected by one or more U.S. or international patents.
