MAX14813

Ultra-Compact Octal 3L/Quad 5L Pulser with

T/R Switches and Beamforming Capability

General Description

Beneﬁts and Features

● Optimized for Compact and Portable Applications

• High Density Eight Channels 3 Levels Pulser in a

6.33mm x 6.65mm WLP

The MAX14813 is a very high density, high-voltage

ultrasound transmitter (pulser) in a wafer-level package

(WLP). It is particularly aimed to address ultrasound

imaging applications in which PCB space is a concern.

• Integrated Low-Power, Low-Noise, Active T/R Switches

• Direct-Drive Architecture Eliminates External Floating

Power Supply (FPS) and HV Signal Capacitors

• Embedded Beamforming Eliminates Transmit

FPGA, Simpliﬁes PCB Layout, and Eases

Synchronization

It features eight 3-level channels operating from two

independent pairs of HV supplies. Each channel

can transmit up to 170V

with up to 2.1A current

P-P

capability. The current capability can be programmed down

to 0.35A with 4 steps of programmability. It also features

an integrated 1A active clamp (Return to Zero).

● Flexibility

• Support Receive Multiplexing

• Can Use Internal/External Beamforming Resources

• Can Operate as Octal 3 Levels or Quad 5 Levels

The MAX14813 can also be configured as a quad 5-levels

(2.1A) pulser plus quad active T/R switches.

The MAX14813 features embedded digital resources

(SRAM and state machine) that can be used to support

transmit beamforming resulting in a dramatic saving of

the number of interconnects and FPGA I/Os. The embed-

ded digital resources are programmed through an high

speed serial interface and supports sophisticated transmit

techniques likewise pulse width modulation for burst-

shaping and apodization for beam shaping.

● Embedded Digital Resources for Beamforming

• 8K Samples (Per Channel) Pulse Wave Table

SRAM Stores Up to 1024 Unique Patterns

• Line Number Memory Stores Beamforming Line

Information For Up To 1.5K Lines (3 Levels) or 3K

Lines (5 Levels)

• 128 Line Type Registers Stores Setting Information

for All the Channels

Alternatively, the device can be controlled in a conventional

manner by an external digital source (FPGA or similar)

through dedicated CMOS logic inputs.

• State Machine for Delay Beamforming with 5ns

Time Resolution

• 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

support Receive Multiplexing in which a fewer number of

receive than transmit channels are used.

● High Performance (Designed to Enhance Image

Quality)

• Excellent Second Harmonic distortion and Pulse

Inversion Performances

• Low Propagation Delay 12ns (typ) Ensures Excel-

lent Phase Noise for Doppler Modes and Excellent

Part-to-Part Matching

The MAX14813 is packaged into a 6.33mm x 6.65mm

WLP, with a 12 x 13 ball grid array.

Applications

● Ultrasound Medical Imaging

● Ultrasound Industrial Applications (NDT)

• Fast Rising Falling Edges Enables Fine Resolution

PWM or Acoustic Power Control

● 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.

● Robustness

• Thermal Warning at 110°C

• Thermal Shutdown at 150°C
