XLR Stereo Audio to E1 Codec

Audio Equipment XLR Stereo Audio To E1 Codec

Overview
E1 Audio Codec is designed by using FPGA digital codec and clock recovery technology. It is applied to broadcasting program source transmission equipment. Audio codec is to frame the stereo audio input signals or AES digital audio signal after A/D digital codec conversion or data format forming a serial data stream output from E1. Audio codec will accept E1 serial data after clock recovery and the split frame recover audio signal stereo audio or AES digital audio output.
Features
◆ Machine design for veneer;
◆ Using FPGA digital codec and clock recovery technology high integration high stability;
◆ Using advanced digital processing clock recovery and digital codec chip. The performance is better;
◆ The panel has LED that indicates E1 stereo and digital audio signal operation condition;
◆ Using SDH PDH microwave 2M channel point to point transmission of audio signal source;
◆ Meet the E1 interface Distributor can achieve one transmission more receive broadcast transmission of  audio signal source;
◆ Applied to province city county and town area group network to realize long distance transmission of audio  signal source;
◆ E1 interface complied with protocol G.703 using digital clock recovery and smooth phase-locked technology;
◆ Audio interface three-level lightning-protection reached IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV   Impedance (2 Ohm) CM(Common Mode): 6KV Impedance (2 Ohm) standard;
◆ AC220V DC-48V/DC24V optional.
