12-Bit, 10.25 GSPS, JESD204B, RF Analog-to-Digital Converter Preliminary Technical Data AD9213 FEATURES
The AD9213 achieves industry leading dynamic range and
High instantaneous dynamic range
linearity performance while consuming only 5 W. Based on an
Noise spectral density 154 dBFS/Hz
interleaved pipeline architecture, the AD9213 features a
SFDR 70 dBc (1 GHz, −1 dBFS)
proprietary calibration and randomization technique that
Low power consumption: 5.1 W at 10 GSPS
suppresses interleaving spurious artifacts into its noise floor.
Integrated input buffer (6.5 GHz input bandwidth)
The excellent linearity performance of the AD9213 is preserved
1.4 V p-p full-scale input with RIN = 50 Ω
by a combination of on-chip dithering and calibration resulting
Overvoltage protection
in excellent spurious free performance over a wide range of
16-lane JESD204B output (up to 16 Gbps line rate)
input signal conditions.
Multichip sync capable with 1 sample accuracy
Applications requiring less instantaneous bandwidth can
DDC NCO synchronization included
benefit from the on-chip digital signal processing (DSP)
Fast overrange detection for efficient AGC
capability of the AD9213 that reduces the output data rate along
Integrated DDC
with the number of JESD204b lanes required to support it. The
Selectable decimation factors
DSP path includes a digital downconverter (DDC) with a 48-bit,
16-profile settings for fast frequency hopping
numerically controlled oscillator (NCO) followed by an I and Q
Optional on-chip PLL clock multiplier
digital decimator stage allowing for selectable decimation rates
On-chip temperature sensor
that are factors of two or three. For fast frequency hopping
On-chip negative voltage generators
applications, the AD9213 NCO supports up to 16-profile settings
Low CER <1e−16
with separate trigger input al owing for wide surveil ance frequency
12 mm × 12 mm BGA
coverage but at a reduced JESD204B lane count.
GENERAL DESCRIPTION
The AD9213 also supports sample accurate multichip The AD9213 is a single 12-bit, 10.25 GSPS, RF analog-to-digital synchronization that also includes synchronization of the converter (ADC) with a 6.5 GHz input bandwidth. The AD9213 NCOs. The AD9213 will be offered in a 192 flip-chip ball grid has been optimized to support high dynamic range frequency array (FcBGA) package. The AD9213 is specified over a and time domain applications requiring wide instantaneous junction temperature range of −10°C to +115°C. bandwidth and low code error rates (CER). The AD9213 features a 16-lane JESD204B interface to support its maximum bandwidth capability.
