Notes:
1. Conditions exceeding the Min or Max values may cause permanent failure. Exposure to conditions near the Min or Max values for extended periods may impair device reliability.
2. Pre-assembly storage in non-drypack conditions is not recommended. Please refer to the instructions on the "CAUTION" label on the drypack bag in which devices are supplied.
3. Test method for ESD per MIL-STD-883D, Method 3015.7.
DescriptionThe TXC-02030 Dual-market Advanced E3/DS3 Receiver/Transmitter (DART) device performs the receive and transmit line interface functions required for transmission of E3 (34.368 Mbit/s) or DS3 (44.736 Mbit/s) signals across a coaxial interface.
The TXC-02030 DART operates from a single +5 volt supply with a minimum number of external components. Performance monitoring, loopbacks, E3/DS3 AIS generation, dejitter FIFO, dejitter PLL, PRBS diagnostic circuits and HDB3/ B3ZS encoding/decoding functions are included.
A single-device solution for interfacing E3 or DS3 signals to DSX cross-connect frames, the DART meets all applicable ANSI, BellCore and ITU-T interconnection specifications for a wide range of system applications. Specifications of TXC-02030 include, but are not limited to ANSI T1.102-1993, ANSI T1.404-1994, GR-499-CORE, ITU-T G.703, G.751, G.755, G.823, and ETSI TBR24.
