.. Octal LNA/VGA/AAF/14-Bit ADC and CW I/Q Demodulator AD9277 APPLICATIONS Medical imaging/ultrasound Automotive radar Features 8 channels of LNA, VGA, AAF, ADC, and I/Q demodulator Low noise preamplifier (LNA) Input-referred noise: 0.75 n V/√Hz typical at 5 MHz (gain = 21.3 d B) SPI-programmable gain: 15.6 d B/17.9 d B/21.3 d B Single-ended input: VIN maximum = 733 m V p-p/ 550 m V p-p/367 m V p-p Dual-mode active input impedance matching Bandwidth (BW) > 100 MHz Full-scale (FS) output: 4.4 V p-p differential Variable gain amplifier (VGA) Attenuator range: - 42 d B to 0 d B Postamp gain: 21 d B/24 d B/27 d B/30 d B Linear-in-d B gain control Antialiasing filter (AAF) Programmable second-order LPF from 8 MHz to 18 MHz Programmable HPF Analog-to-digital converter (ADC) 14 bits at 10 MSPS to 50 MSPS SNR: 73 d B SFDR: 75 d B Serial LVDS (ANSI-644, IEEE 1596.3 reduced range link) Data and frame clock outputs CW mode I/Q demodulator Individual programmable phase rotation Output dynamic range per channel >160 d BFS/√Hz Low power: 207 m W per channel at 14 bits/50 MSPS (TGC), 94 m W per channel for CW Doppler Flexible power-down modes Overload recovery in <10 ns Fast recovery from low power standby mode: <2 μs 100-lead TQFP_EP AVDD1 AVDD2 PDWN PRODUCT HIGHLIGHTS 1. Small Footprint. Eight channels are contained in a small, space-saving package. Full TGC path, ADC, and I/Q demodulator contained within a 100-lead, 16 mm × 16 mm TQFP. Low Power. In TGC mode, low power of 207 m W per channel at 50 MSPS. In CW mode, ultralow power of 94 m W per channel. Integrated High Dynamic Range I/Q Demodulator with Phase Rotation. Ease of Use. A data clock output (DCO±) operates up to 480 MHz and supports double data rate (DDR) operation. User Flexibility. Serial port interface (SPI) control offers a wide range of flexible Features to meet specific system requirements. Integrated Second-Order Antialiasing Filter. This filter is placed before the ADC and is programmable from 8 MHz to 18...
