PT-AECT-IB Module
The AES input front module with TDM capability receives AES3 inputs with amplitude not exceeding 2 V
from 2 Mb/s to 25 Mb/s terminated with 75
with the coaxial back module installed, with amplitude
not exceeding 7 V from 2 Mb/s to 25 Mb/s terminated with 110
with the balanced back module
installed. The front module recovers, reslices, and amplifies the signal before distributing it to the
router’s matrices. This module provides a TDM version of all input signals to be distributed to the audio-
specific crosspoint module or, optionally, it can pass the first eight AES inputs to the wideband
crosspoint. It allows for the connection of 16 channels of AES digital audio using either a balanced or
unbalanced coaxial back module, routed within the Platinum platform. Using the optional 8- or 16-
channel 110
balanced back module (
PT-AEB-IBP
), or 8- or 16-channel 75
coaxial unbalanced back
module (
PT-AEC-IBP
), the AES input front module with TDM will accept up to 16 AES digital audio
signals. Each of the inputs is presented to separate input buffers, which perform the basic signal
recovery and internal conversion to balanced low voltage differential signals (LVDS) for use in the FPGA-
based signal presence detection and router distribution circuitry.
