2 / 53 page  2 IDT82V2058 OCTAL E1 SHORT HAUL LINE INTERFACE UNIT INDUSTRIAL TEMPERATURE RANGES DESCRIPTION The IDT82V2058 is a single chip, 8-channel E1 short haul PCM transceiver with a reference clock of 2.048 MHz. The IDT82V2058 contains 8 transmitters and 8 receivers. All the receivers and transmitters can be programmed to work either in Single Rail mode or Dual Rail mode. HDB3 or AMI encoder/decoder is selectable in Single Rail mode. Pre-encoded transmit data in NRZ format can be accepted when the device is configured in Dual Rail mode. The receivers perform clock and data recovery by using inte- grated digital phase-locked loop. As an option, the raw sliced data (no retiming) can be output on the receive data pins. Transmit equalization is implemented with low-impedance output drivers that provide shaped waveforms to the transformer, guaranteeing template conformance. A jitter attenuator is integrated in the IDT82V2058 and can be switched into either the transmit path or the receive path for all channels. The jitter attenuation performance meets ETSI CTR12/13, ITU G.736, G.742 and G.823 specifications. The IDT82V2058 offers hardware control mode and software control mode. Software control mode works with either serial host interface or parallel host interface. The latter works via an Intel/Motorola compatible 8-bit parallel interface for both multiplexed or non-multiplexed applica- tions. Hardware control mode uses multiplexed pins to select different operation modes when the host interface is not available to the device. The IDT82V2058 also provides loopback and JTAG boundary scan testing functions. Using the integrated monitoring function, the IDT82V2058 can be configured as a 7-channel transceiver with non- intrusive protected monitoring points. The IDT82V2058 can be used for SDH/SONET multiplexers, central office or PBX, digital access cross connects, digital radio base stations, remote wireless modules and microwave transmission systems.
