• Product Introduction

AD6641-500EBZ 250 MHz bandwidth DPD observation receiver

The AD6641 is a 250 MHz bandwidth digital predistortion observation receiver that integrates a 12-bit 500 MSPS ADC, a 16k × 12 FIFO, and a multi-mode back-end that allows users to retrieve data stored in the integrated FIFO memory via a serial port (SPORT), SPI interface, or 12-bit parallel CMOS/6-bit DDR LVDS port. It offers excellent dynamic performance and low power consumption, making it suitable for telecom applications such as digital pre-distortion observation paths that require wider bandwidth. All required functions are integrated on-chip, including a sample retainer and a voltage reference, to provide a complete signal conversion solution.

The on-chip FIFO allows for shorter time snapshots to be captured via the ADC and readback at a lower rate. This allows the captured data to be transmitted at any time at a much lower sample rate, reducing signal processing limitations. FIFO can work in a variety of user-programmable modes. In single-capture mode, ADC data is captured when signaling through the SPI port or when using an external FILL ± pin. In continuous capture mode, the data is continuously loaded into the FIFO and the operation is stopped using the FILL ± pin.
