产品详情

The AD9213 is a single 12-bit, 10.25 GSPS, RF analog-to-digital converter (ADC) with a 6.5 GHz input bandwidth. The AD9213 has been optimized to support high dynamic range frequency and time domain applications requiring wide instantaneous bandwidth and low code error rates (CER). The AD9213 features a 16-lane JESD204B interface to support its maximum bandwidth capability.

The AD9213 achieves industry leading dynamic range and linearity performance while consuming only 5 W. Based on an interleaved pipeline architecture, the AD9213 features a proprietary calibration and randomization technique that suppresses interleaving spurious artifacts into its noise floor. The excellent linearity performance of the AD9213 under low level signal conditions is preserved by a combination of on-chip dithering and calibration resulting in excellent windowed spurious free performance (<−95 dBFS) over a wide range of input signal conditions.

Applications requiring less instantaneous bandwidth can benefit from the on-chip digital signal processing (DSP) capability of the AD9213 that reduces the output data rate along with the number of JESD204b lanes required to support it. The DSP path includes a digital downconverter (DDC) with a 48-bit, numerically controlled oscillator (NCO) followed by an I and Q digital decimator stage allowing for selectable decimation rates that are factors of two or three. For fast frequency hopping applications, the AD9213 NCO supports up to 16-profile settings with separate trigger input allowing for wide surveillance frequency coverage but at a reduced JESD204B lane count.

The AD9213 also supports sample accurate multichip synchronization that also includes synchronization of the NCOs. The AD9213 will be offered in a 192 flip-chip ball grid array (FcBGA) package. The AD9213 is specified over a junction temperature range of −10°C to +115°C.
