AD9561 - Pulse Width Modulator

Description

The AD9561 is a second generation high speed, digitally programmable pulse width modulator (PWM).

Output pulse width is proportional to an 8-bit DATA input value.

Two additional control inputs determine if the pulse is placed at the beginning, middle or end of the clock period.

Features

  • 60 MHz Pulse Rate 8-Bit Resolution Center, Left or Right Justify Low Power: 700 mW typical Minimum Pulse Width:.
