12-Bit, 6 GSPS/10.25 GSPS, RF Analog-to-Digital Converter

The AD9217 is a single, 12-bit, 6 GSPS/10.25 GSPS, radio frequency (RF) analog-to-digital converter (ADC) with a 6.5 GHz input bandwidth. The AD9217 supports high dynamic range frequency and time domain applications requiring wide instantaneous bandwidth and low conversion error rates (CER).

The AD9217 features a low latency, high speed, parallel CML output interface that supports full bandwidth operation with compatible FPGA/ASIC receivers. The AD9217 can be reconfigured to operate in native AD9213 mode for applications requiring additional digital processing and JESD204B output support. Refer to the AD9213 data sheet when operating the AD9217 in AD9213 mode.

The AD9217 achieves dynamic range and linearity performance while consuming 4.2 W typical. The device is based on an interleaved pipeline architecture and features a proprietary calibration and randomization technique that suppresses interleaving spurious artifacts into its noise floor. The linearity performance of the AD9217 is preserved by a combination of on-chip dithering and calibration, which results in excellent spurious-free performance over a wide range of input signal conditions.

The AD9217 is offered in a 192-ball ball grid array (BGA) package and is specified over a junction temperature range of −20°C to +115°C.
