Product details
Overview
IDT82V2058 from Integrated Device Technology (IDT) is an octal E1 short-haul line interface unit supporting 120 Ω twisted-pair and 75 Ω coaxial transmission, featuring integrated 8-channel transceivers with 2.048 MHz reference clock, selectable AMI/HDB3 encoding/decoding, and built-in jitter attenuator meeting ITU G.736/G.742/G.823 and ETSI CTR12/13 standards. It serves in digital access cross-connects and PBX systems requiring precise E1 signal conditioning.
For engineers reviewing the IDT82V2058 datasheet, IDT82V2058 pinout, IDT82V2058 application, or IDT82V2058 equivalent, key selection criteria include per-channel transmit/receive jitter attenuation path selection, hardware vs. serial/parallel host interface configuration, G.772 non-intrusive monitoring capability for channels 1–7, and dual-rail/single-rail mode flexibility with NRZ input/output mapping.
Technical Context
The IDT82V2058 implements a digital phase-locked loop (DPLL) for clock and data recovery on all eight receive channels, with optional raw sliced data output (no retiming) via RDPn/RDNn pins. Its transmit path includes low-impedance drivers with waveform shaping to meet G.703 template compliance and pre-equalization for short-haul E1 lines.
Jitter attenuation is configurable per channel into either transmit or receive path using JAS control, satisfying SONET/SDH-aligned ITU G.783 mapping jitter requirements. The device supports three system interface modes: Single Rail (AMI/HDB3), Dual Rail with clock recovery, and Dual Rail with data recovery (RZ slicing only), each with distinct pin assignments and timing relationships.

Equivalent & Alternatives
The following parts are listed as comparable options for similar E1 line interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Maxim MAX3005 | Quad-channel (not octal); no G.772 monitoring; fixed HDB3-only encoding | Limited to 4 E1 links; lacks non-intrusive monitoring and hardware mode flexibility | Choose for cost-sensitive quad-E1 designs where monitoring and mode flexibility are not required |
| Microchip ZL30122 | Single-channel E1 LIU; integrates Ethernet framer; requires external jitter cleaner for G.783 compliance | Designed for packet/E1 hybrid gateways; adds Ethernet MAC but increases system complexity | Prefer when combining E1 termination with packet processing; avoid when pure octal E1 density is critical |
Compared with MAX3005 and ZL30122, the IDT82V2058 delivers higher channel density (8×), native G.772 monitoring, and true hardware-mode configurability-making it optimal for space-constrained central office and cross-connect applications requiring full E1 link autonomy.

FAQ
What is the primary function of the IDT82V2058 in E1 systems?
The IDT82V2058 serves as a fully integrated octal E1 short-haul line interface unit, performing bidirectional conversion between digital system-side NRZ data and bipolar E1 line signals (AMI/HDB3) across eight independent channels. It handles clock recovery, jitter attenuation, line driving, and LOS detection-all within a single IC. Each channel of the IDT82V2058 operates autonomously, supporting flexible configuration for diverse telecom infrastructure deployments.
Does the IDT82V2058 support both 120 Ω and 75 Ω E1 physical layers?
Yes, the IDT82V2058 supports both 120 Ω twisted-pair and 75 Ω coaxial E1 interfaces through its programmable line driver architecture and configurable receive termination. The TTIPn/TRINGn outputs and RTIPn/RRINGn inputs are designed to interface directly with standard E1 transformers or baluns for either impedance type without external component changes. This dual-impedance capability is explicitly confirmed in the device's functional description and feature list.
How does the G.772 non-intrusive monitoring work on the IDT82V2058?
The IDT82V2058 implements G.772-compliant non-intrusive monitoring by internally routing analog line signals from any selected channel (1–7) to the dedicated monitoring channel (channel 0) via RTIP0/RRING0. Configuration is done using the MC[3:0] pins in hardware mode or register writes in host mode. The monitored signal appears on RDP0/RDN0 as raw RZ-sliced data, enabling in-service testing without disrupting live traffic on the source channel-verified in the functional block diagram and pin description tables.
Can the IDT82V2058 operate without a microcontroller interface?
Yes, the IDT82V2058 supports full hardware mode operation using dedicated control pins (MODE[2:0], LP[7:0], CODE, JAS, OE) without requiring a serial or parallel host processor. In this mode, functions like loopback selection, line code choice (AMI/HDB3), jitter attenuator path, and output enable are set statically via pin strapping. This enables standalone deployment in systems where firmware control is unavailable or undesirable-explicitly documented in Table-2 and Section 2.1.1.
What package options are available for the IDT82V2058?
The IDT82V2058 is offered in two RoHS-compliant packages: a 144-pin Thin Quad Flat Pack (TQFP) and a 160-pin Plastic Ball Grid Array (PBGA). Both packages provide identical electrical functionality and pin-to-pin compatibility across all channels and interfaces. Pin assignments differ between packages but follow consistent grouping (e.g., TTIPn/TRINGn pairs occupy analogous positions), and thermal/mechanical design guidelines are provided separately for each in the datasheet.
