MAX14813 Ultra-Compact Octal 3L/Quad 5L Pulser with T/R Switches and Beamforming Capability General Description Benefits and Features The MAX14813 is a very high density, high-voltage Optimized for Compact and Portable Applications ultrasound transmitter (pulser) in a wafer-level package High Density Eight Channels 3 Levels Pulser in a (WLP). It is particularly aimed to address ultrasound 6.33mm x 6.65mm WLP Integrated Low-Power, Low-Noise, Active T/R Switches imaging applications in which PCB space is a concern. Direct-Drive Architecture Eliminates External Floating It features eight 3-level channels operating from two Power Supply (FPS) and HV Signal Capacitors independent pairs of HV supplies. Each channel Embedded Beamforming Eliminates Transmit can transmit up to 170V with up to 2.1A current P-P FPGA, Simplifies PCB Layout, and Eases capability. The current capability can be programmed down Synchronization to 0.35A with 4 steps of programmability. It also features an integrated 1A active clamp (Return to Zero). Flexibility Support Receive Multiplexing The MAX14813 can also be configured as a quad 5-levels Can Use Internal/External Beamforming Resources (2.1A) pulser plus quad active T/R switches. Can Operate as Octal 3 Levels or Quad 5 Levels The MAX14813 features embedded digital resources Embedded Digital Resources for Beamforming (SRAM and state machine) that can be used to support 8K Samples (Per Channel) Pulse Wave Table transmit beamforming resulting in a dramatic saving of SRAM Stores Up to 1024 Unique Patterns the number of interconnects and FPGA I/Os. The embed- Line Number Memory Stores Beamforming Line ded digital resources are programmed through an high Information For Up To 1.5K Lines (3 Levels) or 3K speed serial interface and supports sophisticated transmit Lines (5 Levels) techniques likewise pulse width modulation for burst- 128 Line Type Registers Stores Setting Information shaping and apodization for beam shaping. for All the Channels Alternatively, the device can be controlled in a conventional State Machine for Delay Beamforming with 5ns manner by an external digital source (FPGA or similar) Time Resolution through dedicated CMOS logic inputs. Programmable Number of Cycles and Pattern Time Base (Pulse Width) The MAX14813 features independent active T/R switches. The T/R switches can possibly be externally configured to High Performance (Designed to Enhance Image support Receive Multiplexing in which a fewer number of Quality) receive than transmit channels are used. Excellent Second Harmonic distortion and Pulse Inversion Performances The MAX14813 is packaged into a 6.33mm x 6.65mm Low Propagation Delay 12ns (typ) Ensures Excel- WLP, with a 12 x 13 ball grid array. lent Phase Noise for Doppler Modes and Excellent Part-to-Part Matching Applications Fast Rising Falling Edges Enables Fine Resolution Ultrasound Medical Imaging PWM or Acoustic Power Control Ultrasound Industrial Applications (NDT) Low Power Low Quiescent Power Dissipation (4.1mW/Channel in Octal Mode) Programmable Current Capability Down to 0.35A for CWD and Low-Voltage Modes Ordering Information appears at end of data sheet.
