PEF2256H V2.2 Product Details

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. 

 Due to its multitude of implemented functions, it fits to a wide range of networking applications and fulfills the according international standards. Three integrated signaling controllers including Signaling System #7 (SS7) support reduces software overhead. 

Crystal-less jitter attenuation with only one master clock source, integrated receive line termination, and an analog switch reduce the amount of required external components. 

Equipped with a flexible microprocessor interface, it connects to any control processor environment. A standard boundary scan interface is provided to support board level testing. Flat pack or BGA device packaging, minimum number of external components and low power consumption lead to reduced overall system costs.


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)
