The AD9213 from Analog Device is a single 12-bit, 10.25 GSPS RF analog-to-digital converter (ADC) with a 6.5 GHz input bandwidth. It has a 16-lane JESD204B interface to support its maximum bandwidth capability. The ADC achieves high dynamic range and linearity performance while consuming only 5 W of power. The DSP path includes a digital down converter (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 ADC also supports sample accurate multichip synchronization that includes synchronization of the NCOs. It is available in a 192 flip-chip ball grid array (FcBGA) package and is ideal for radar, military communications, spectrum analyzers and jamming applications.
