Model 5402
DANTE LEADER CLOCK WITH GNSS SYNCHRONIZATION
Specifications
Applications:
GNSS (satellite) time-referenced, high-performance
Leader clock for Dante audio-over-IP applications. Also
supports AES67-2018 applications. In addition, provides
audio tones on Dante transmitter (output) channels for
general-purpose use and a word clock synchronization
output.
