General Description
The Supertex HV7351 is an 8-channel programmable high
voltage ultrasound transmit beamformer. Each channel is
capable of swinging up to ±70V with an active discharge back
to 0V. The outputs can source and sink more than 3.0A to
achieve fast output rise and fall times. The active discharge is
also capable of sourcing and sinking 3.0A for a fast return to
ground. The topology of the HV7351 will significantly reduce
the number of I/O logic control lines needed.
Each pulser has four associated 64-bit shift registers for
storing pre-determined transmit patterns and a 10-bit delay
counter for controlling the transmit time. One of four arbitrary
patterns can be transmitted with adjustable delay, depending
on the data loaded into these shift registers and the delay
counter. The delay counter can be clocked up to 200MHz,
allowing incremental delays down to 5ns.
