EVALUATION KIT AVAILABLE MAX2082 Low-Power, High-Performance Octal Ultrasound Transceiver with Integrated AFE, Pulser, T/R Switch, and CWD Beamformer General Description Benefits and Features Minimizes PCB Area and Design Cost The MAX2082 is the worlds first fully-integrated octal 8 Full Channels of HV Pulser, T/R-Switch, LNA ultrasound transceiver. The device is optimized for high- Input and Feedback Coupling Caps, LNA, VGA, channel-count, high-performance portable and cart-based AAF, CWD Mixers, 12-Bit ADC, and Digital HPF in ultrasound systems. The easy-to-use transceiver allows a Small 10mm x 23mm CSBGA Package the user to achieve high-end 2D and Doppler imaging capability using substantially less space and power. Integrated HV Pulser for Simpler System Design High-Voltage 3 Level Pulsers (Up to 105V) with The transceiver transmitters are high-performance, 3-level Active Return to Zero and Internal Power-Supply 2A pulsers capable of generating high-voltage pulses up Drivers for Reduced External Components to 105V. Programmable Pulser Current Capability from 0.5A The highly compact receiver with T/R switch, LNA, input to 2A for Reduced Power Consumption in Lower coupling and feedback capacitors, variable gain amplifier Voltage Transmit Modes Like CWD (VGA), anti-aliasing filter (AAF), analog-to-digital con- Extremely Low Propagation Delay Pulsers (18ns) verter (ADC), and digital highpass filter (HPF) achieves with Excellent Rise and Fall Matching for Excellent an ultra-low noise figure with R = R = 200 at a very S IN THD2 Performance (-43dBc at 5MHz) low 131mW per-channel power dissipation at 50Msps. The receive channel has been optimized for second Integrated High-Performance Receiver Improves System Sensitivity harmonic imaging with -66dBFS second harmonic distor- tion performance at f = 5MHz over the full gain range. Ultra-Low Full-Channel Receiver Noise Figure RF The full receive channel exhibits an exceptional 76dBFS of 2.8dB at R = R = 200 (Without T/R Switch) IN S SNR at 5MHz with a 2MHz bandwidth. High Dynamic Range Receiver with 76dBFS SNR at f = 5MHz and 2MHz Bandwidth IN Separate mixers for each channel are made avail- Ultra-Low Power Receiver (131mW Per Channel) able for optimal CWD sensitivity yielding an impressive 149dBc/Hz dynamic range per channel at 1kHz offset Applications from the 1.25MHz carrier. Ultrasound Imaging The MAX2082 octal ultrasound front-end is available in a small 10mm x 23mm CSBGA package and is specified Ordering Information appears at end of data sheet. over a 0C to +70C temperature range. 19-6601 Rev 0 9/14MAX2082 Low-Power, High-Performance Octal Ultrasound Transceiver with Integrated AFE, Pulser, T/R Switch, and CWD Beamformer Typical Application Circuit Maxim Integrated 2 www.maximintegrated.com 11V OPTIONAL AVDD 10V, -HV0 33H 33H 33H 33H TVEE VCC3 120 120 120 120 1F TINP1 TINP2 TINP3 TINP4 TMODE0 TCC0 100nF 100nF 100nF 10V, TINN1 TINN2 TINN3 TINN4 TMODE1 TCC1 LO+ LO- LOON CWD SHDN +HV0 TVCC TVDD V OVDD CC5 1F 100nF 100nF A2 A3 A4 B4 A5 B5 B6 A6 B7 A7 B8 A8 B9 A9 A10 A11 B11 A12 B12 B16 C16 D16 E16 F18 G18 A19 B19 A20 B20 A21 B21 A22 B22 B23 A23 B24 A24 A25 B25 A26 B26 A28 OUT1+ TR1 B27 OUT1+ B1 B2 B3 OUT1- TR2 B28 OUT1- C1 C2 C3 OUT2+ TR3 C27 OUT2+ D1 D2 D3 OUT2- TR4 C28 OUT2- E1 E2 E3 OUT3+ D27 OUT3+ OUT3- D28 OUT3- OUT4+ A1 A13 A14 A15 A16 A17 A18 A27 E27 OUT4+ OUT4- B10 B13 B14 B15 B17 B18 E28 OUT4- CLKOUT+ C4 C5 C6 C7 C8 C9 C10 C11 C12 C13 C14 C15 C17 C18 C19 C20 C21 C22 C23 C24 C25 C26 F27 CLKOUT+ CLKOUT- D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 D17 D18 D19 D20 D21 D22 D23 D24 D25 D26 F28 CLKOUT- OVDD OVDD E4 E5 E6 E7 E8 E9 E10 E11 E12 E13 E14 E15 E17 E18 E19 E20 E21 E22 E23 E24 E25 E26 F26 100nF OVDD F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14 F15 F16 F17 F19 F20 F21 F22 F23 F24 F25 G26 G1 G2 G3 G4 G5 G6 G7 G8 G9 G10 G11 G12 G13 G14 G15 G16 G17 G19 G20 G21 G22 G23 G24 G25 FRAME+ H4 H5 H6 H7 H8 H9 H10 H11 H12 H13 H14 H15 H17 H18 H19 H20 H21 H22 H23 H24 H25 H26 G27 FRAME+ FRAME- J4 J5 J6 J7 J8 J9 J10 J11 J12 J13 J14 J15 J17 J18 J19 J20 J21 J22 J23 J24 J25 J26 G28 FRAME- OUT5+ K4 K5 K6 K7 K8 K9 K10 K11 K12 K13 K14 K15 K17 K18 K19 K20 K21 K22 K23 K24 K25 K26 H27 OUT5+ OUT5- L13 L14 L15 L17 L18 L25 H28 OUT5- OUT6+ M1 M13 M14 M15 M16 M17 M18 M25 J27 OUT6+ OUT6- J28 OUT6- TR5 H1 H2 H3 OUT7+ K27 OUT7+ GND BUMPS TR6 J1 J2 J3 OUT7- K28 OUT7- TR7 K1 K2 K3 OUT8+ L27 OUT8+ TR8 L1 L2 L3 OUT8- L28 OUT8- M2 M3 M4 L4 M5 L5 L6 M6 L7 M7 L8 M8 L9 M9 M10 L10 L11 M11 M12 L12 L16 K16 J16 H16 L19 M19 M20 L20 L21 M21 L22 M22 L23 M23 L24 M24 L26 M26 M27 M28 +HV0 TVCC TVDD VCC5 AVDD OVDD 100nF 100nF 100nF 100nF 10V, 100nF 1mF -HV0 TINN5 TINN6 TINN7 TINN8 TTHP TCLK+ V V V CLKIN+ CS TVEE REF G- G+ SDIO V TINP5 TINP6 TINP7 TINP8 TSYNC TCLK- CC3 CLKIN- SCLK TEN 10V, 33H 33H 33H 33H 1mF 100nF 100nF OPTIONAL TVNNB TVNNA TVPPB TVPPA TVGPB TVGPA TVGNB TVGNA TVEE TVEE TVCC TVCC TINN5 TINN1 TINP5 TINP1 TINN6 TINN2 TINP6 TINP2 TINN7 TINN3 TINP7 TINP3 TINN8 TINN4 TINP8 TINP4 TVDD TVDD TEN TMODE1 TTHP TMODE0 TSYNC TCC1 TCLK+ TCC0 TCLK- INB1 INB8 INB2 INB7 INB3 INB6 INB4 INB5 AG VCC5 AG V V CC5 CC3 VCC5 VCC5 CI+ VREF VG- CI- VG+ CQ+ VCC3 CQ- VCC3 LO+ LO- AVDD LOON AVDD AVDD AVDD CLKIN+ N.C.
