500DA-AESB - 1
1. OVERVIEW
The 500DA-AESB is a four output reclocking and auto equalizing DA for unbalanced 110 ohm AES
signals. The DA automatically equalizes up to 300m of Belden 1800B cable and provides reclocked
outputs with sampling frequencies of 32kHz, 44.1kHz, 48kHz and 96kHz.
The 500DA-AESB card edge LED indicators provide quick and accurate assessment of the incoming
signal integrity.
The 500DA-AESU is housed in the 500FR
Frame that will hold up to 16 modules.
Features:
•
Supports AES3-1992 standard for AES audio on 110 twisted pair cable
•
Automatic equalization and reclock provide extended cable length compensation (>300m)
•
Transformer coupled balanced input
•
High impedance or 110 ohm termination on input (jumper selectable)
•
4 reclocked outputs provide jitter reduction
•
Card edge indicators for AES present, Reclocker rate, and AES Validity bit
•
Tally output to Frame Status connector for input error conditions
