8911 Instruction Manual 3
Specifications
The outputs feed a resistive network that performs three functions:
■ Attenuates the signal to become 1 volt peak-to-peak,
■ Creates a 75 Ω output resistance matching the cable impedance, and
■ Limits the rise and fall times to meet the AES/EBU specification.
Linear Regulator
The voltage regulator is a monolithic integrated circuit with a fixed voltage
output of +5 volts. This regulator employs internal current limiting and
thermal shutdown.
