PEF2256規(guī)格書詳情
Introduction
The FALC?56 framer and line interface component is designed to fulfill all required interfacing between analog E1/T1/J1 lines and the digital PCM system highway, H.100/H.110 or H-MVIP bus for world market telecommunication systems.
Features
Line Interface
? High-density, generic interface for all E1/T1/J1 applications
? Analog receive and transmit circuits for long-haul and short-haul applications
? E1 or T1/J1 mode selectable
? Data and clock recovery using an integrated digital phase-locked loop
? Maximum line attenuation up to -43 dB at 1024 kHz (E1) and up to -36 dB at 772 kHz (T1/J1)
? Programmable receive equalizer characteristic
? Software-selectable receive line termination
? Programmable transmit pulse shapes for E1 and T1/J1 pulse masks
? Programmable line build-out for CSU signals according to ANSI T1. 403 and FCC68: 0dB, -7.5 dB, -15 dB, -22.5 dB (T1/J1)
? Low transmitter output impedances for high transmit return loss
? Tristate function of the analog transmit line outputs
? Analog switch for redundancy applications
? Transmit line monitor protecting the device from damage
? Receive line monitor mode
? Jitter specifications of ITU-T I.431, G.703, G.736 (E1), G.823 (E1) and AT&T TR62411 (T1/J1) are met
? Crystal-less wander and jitter attenuation/compensation
? Common master clock reference for E1 and T1/J1 (any frequency within 1.02 and 20 MHz)
? Power-down function
? Support of automatic protection switching
? Dual-rail or single-rail digital inputs and outputs
? Unipolar NRZ or CMI for interfacing fiber-optical transmission routes
? Selectable line codes (E1: HDB3, AMI/T1: B8ZS, AMI with ZCS)
? Loss-of-signal indication with programmable thresholds according to ITU-T G.775, ETS300233 (E1) and ANSI T1.403 (T1/J1)
? Optional data stream muting upon LOS detection
? Programmable receive slicer threshold
? Clock generator for jitter-free system/transmit clocks per channel
? Local loop and remote loop for diagnostic purposes
? Low power device
? Single power supply (3.3 V) or dual power supply (3.3 V and 1.8 V)
