MaxLinear has a comprehensive and broad T/E/J physical layer product portfolio: Line Interface Units (LIUs), Analog Front Ends (AFEs), framers, LIU/ framer combos, LIU/Jitter Attenuator Combos (with and without Desynchronization), BITS clock receivers and transceivers, and PCM line interfaces. Our products provide bridging solutions from existing networks to EoPDH, Circuit Emulation (CES) and Pseudo Wire (PWE) applications as well as providing synchronization for Ethernet networks through our BITS solutions. Exar has a history of innovation with many industry firsts:

R³ Technology™ (Reconfigurable, Relayless Redundancy)

An 8-Channel integrated LIU/Framer device, replaces several discrete components

Up to 14-Channel long/short haul T1 LIU, (21-Channel for E1)

A 28-Channel T1/E1 LIU/Framer with VT/TU Mapper and M13 Multiplexer

Up to 12-Channel T3/E3 LIU

PDH Framer and LIU Solutions

MaxLinear has a great reputation for offering innovative T1/E1/J1 as well as T3/E3/STS-1 products with many industry firsts, including the single-chip Jitter Attenuators (JA), integrated LIU with JA and CDR (Clock and Data recovery), and an integrated LIU plus SONET/SDH desynchronizer. The LIU function incorporates the R³ (Relayless, Reconfigurable Redundancy) Technology™ for minimal footprint and cost effective solutions. MaxLinear is well known for outstanding product reliability and design support over a wide range of devices. Used individually or in chipsets, these devices are used in systems for many of the leading networking equipment manufacturers.

Another family of Framer / Mapper products provide flexible mapping of multi-channel T1/E1 clients into SONET/SDH networks. The highest density product in this family provides mapping of 28 independent T1s (or 21 E1s) into an STS-1. It also supports the transparent transfer and regeneration of the independent T1/E1 clocks across the SONET/SDH network and meets all the jitter / wanders specs of the T1/E1 client interfaces.

MaxLinear PDH Technology Advantages

MaxLinear offers many advantages to system designers. Key among these are features that provide flexibility in design, enable system reliability, reduce cost, and provide standards compliant solutions.

R³ Technology™

R³ Technology™ means Reconfigurable, Relayless Redundancy. Designers can configure or reconfigure a card (board) in software without changing any external components.

Reduces time-to-market/manufacturing costs

Allows single Bill-of-Material (BOM) for worldwide applications

Employing a full suite of loop-backs, MaxLinear devices can quickly identify a fault location, invoke a complete set of alarms, and easily determine the fault type for the network operator. This detection and diagnostic capability is critical to reliable data transmission. MaxLinear's PDH products have the several client and facility side loop-backs for each function providing designers with a built-in diagnostic solution for the physical layer. A suite of Performance Monitoring (PMON) counters keep track of the integrity of each of section of the links.

Temperature

All of MaxLinear's T/E Carrier and DS3/E3 products are industrial grade with a temperature of -40ºC to +85ºC.

Innovative Features

Redundancy Internal switches help to implement 1:1 or 1+1 redundancy without the need for any relays, which helps to reduce cost and board space while improving reliability.

Hot Swapping MaxLinear's LIUs not only support 1:1 or 1+1 redundancy, but also support hot swapping without relays.

Integrated Timing Generators An on-board timing circuit generates the appropriate system clocks from a single crystal. This again eliminates the need to change any components externally.

Design Flexibility Choice of Host (software) or Hardware mode for interfacing and control provide design flexibility.

Extensive Diagnostic Capability System users can quickly isolate a fault location, use alarms, and determine the nature of the fault.

Applications of T1/E1/J1 and T3/E3/STS-1 products

MaxLinear's world-class physical layer solutions are ideal for a wide variety of markets and applications:
