Product details
Overview
82P2282PFG8 from Integrated Device Technology is a dual-channel T1/E1/J1 long-haul and short-haul line transceiver IC supporting simultaneous operation in T1 (1.544 Mbps), E1 (2.048 Mbps), and J1 (1.544 Mbps) modes with adaptive equalization, jitter attenuation, and full frame processing. It integrates receiver and transmitter paths per channel, supports SF/ESF/T1-DM/SLC-96 and E1 basic/CRC/CAS multi-frame formats, and targets telecom access equipment requiring carrier-grade timing integrity and protocol flexibility.
For engineers reviewing the 82P2282PFG8 datasheet, 82P2282PFG8 pinout, 82P2282PFG8 application, or 82P2282PFG8 equivalent, key selection criteria include dual-port T1/E1/J1 compatibility, programmable line build-out, HDLC channel support, elastic store buffering, and integrated alarm detection for legacy circuit-switched infrastructure.
Technical Context
The 82P2282PFG8 implements two independent transceiver channels, each with fully configurable receive path (adaptive equalizer, data slicer, CDR, jitter attenuator, decoder, frame processor) and transmit path (encoder, waveform shaper, line driver). It supports both long-haul (0–655 ft, 75 Ω/120 Ω) and short-haul (0–400 ft, 100 Ω) line impedances per channel via programmable termination and LBO control.
Each channel handles T1/E1/J1 framing autonomously: T1/J1 supports Super Frame (SF), Extended Super Frame (ESF), Digital Multiplexer (DM), and SLC-96; E1 supports Basic Frame, CRC Multi-Frame, and CAS Signaling Multi-Frame. HDLC receiver/transmitter and bit-oriented message handling are available per channel with dedicated interrupt reporting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 1.544 Mbps (T1/J1) or 2.048 Mbps (E1) per channel - enables dual-protocol interoperability in same device without external rate conversion. |
| Line Interface | Dual independent ports with selectable 75 Ω/100 Ω/120 Ω termination - supports mixed T1 (100 Ω) and E1 (75 Ω or 120 Ω) deployments on single chip. |
| Equalization | Adaptive analog equalizer per receive channel - compensates up to 655 ft of T1 cable loss without manual tuning or external components. |
| Jitter Attenuation | Integrated receive jitter attenuator with ≤1.5 UI peak-to-peak output jitter - meets GR-499-CORE long-haul jitter compliance for T1/E1 interfaces. |
| Framing Support | T1: SF, ESF, DM, SLC-96; E1: Basic, CRC, CAS - eliminates need for separate framing ASICs in multi-standard access gateways. |
| HDLC Channels | Two independent HDLC receivers/transmitters - supports embedded OAM channel handling and D-channel signaling in ISDN or DSLAM applications. |
| Power Supply | 3.3 V core + 3.3 V I/O - compatible with standard telecom logic rails and simplifies power sequencing in line card designs. |
Pinout & Package
82P2282PFG8 is housed in a 128-pin LQFP package (14 mm × 14 mm, 0.4 mm pitch) with exposed thermal pad. Pin functions are organized into dual-channel groups: RXP/RXN (differential receive inputs), TXP/TXN (differential transmit outputs), MRSD/MRSIG (multiplexed receive status/data), and dedicated clock, control, and interrupt pins per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RXP0 / RXN0 | Differential receive input (Channel 0) | Accepts balanced T1/E1/J1 line signal; internally terminated to 100 Ω or 120 Ω depending on mode configuration. |
| TXP0 / TXN0 | Differential transmit output (Channel 0) | Drives line with programmable amplitude and rise/fall time; supports long-haul (−15 dBm) and short-haul (0 dBm) levels. |
| MRSD0 / MRSIG0 | Multiplexed receive status/data bus (Channel 0) | Time-multiplexed interface for frame sync, LOS, AIS, and payload data - reduces pin count vs. parallel bus implementation. |
| CLKIN0 / CLKOUT0 | Receive clock reference and output (Channel 0) | Supports clock master/slave/multiplexed modes; CLKOUT0 provides recovered or regenerated clock for downstream logic synchronization. |
| INT0 / INT1 | Interrupt outputs (per channel) | Assert active-low on LOS, AIS, LOF, RAI, or HDLC frame error - enables real-time fault isolation without polling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent T1/E1/J1 transceivers | Enables single-chip support for mixed TDM line cards-e.g., one port as T1 DSU, second as E1 access node-without inter-channel crosstalk or shared resource contention. |
| Programmable line build-out (LBO) | Adjusts transmit drive strength and slew rate per channel to match cable length and impedance, eliminating external line drivers in short-haul deployments. |
| Elastic store buffer with 256-byte depth | Compensates for frequency offset between line clock and system clock, enabling seamless bridging between asynchronous T1/E1 networks and synchronous backplane buses. |
| Integrated HDLC receiver/transmitter | Handles D-channel or OAM signaling at 64 kbps without external controller-reduces firmware overhead and latency in embedded management stacks. |
| Comprehensive alarm detection suite | Monitors LOS, AIS, LOF, RAI, BPV, and CRC errors per channel with dedicated interrupt flags-accelerates fault localization in carrier-class SLA monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar T1/E1/J1 transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Maxim MAX5864 | Single-port T1/E1 transceiver; no J1 support; fixed 75 Ω termination only; no HDLC engine. | Suitable for cost-sensitive E1-only edge devices but lacks dual-port redundancy and J1 compatibility required for North American deployments. | Select when only one line interface is needed and J1 or HDLC is not required-reduces footprint and power by ~30%. |
| TI TLK2201B | Serial RapidIO-to-T1/E1 bridge; requires external framing logic; no adaptive equalization; supports only E1/T1, no J1. | Targets high-speed packet backplanes interfacing with TDM networks-not standalone line interface replacement. | Choose only if integrating with SRIO-based control plane; otherwise, 82P2282PFG8 offers complete self-contained solution with lower system complexity. |
Compared with MAX5864 and TLK2201B, the 82P2282PFG8 uniquely delivers dual independent T1/E1/J1 support with integrated framing, HDLC, and adaptive equalization-making it the only option for carrier-grade dual-standard line cards requiring zero external signal conditioning.
