PEF2426HV1.1 - Brand New Infineon Telecommunication Interface ICs
-
Overview
The four-channel codec filter PEB 2466 SICOFI®4-µC is built around a central DSP-core which provides independent filter structures for all channels. Its analog I/O pins are used to connect to external subscriber line interface circuits (SLICs). Their signals are internally routed to the analog-to-digital and digital-to-analog converters (ADC, DAC).
Features
• Four-channel single chip codec with digital filters
• High analog driving capability (300 Ω, 50 pF) for direct driving of transformers
• Digital Signal Processing (DSP) technique
• Programmable digital filters to adapt transmission behavior, especially for:
– AC impedance matching
– Transhybrid balancing
– Frequency response
– Signal levels
– A/µ-Law compression and expansion
• Fulfills international (e.g. ITU-T Q.552, G.712) and country-specific requirements
• High performance ADC and DAC for excellent linearity and dynamic gain
• Programmable Analog Interface to electronic SLICs or transformer solutions
• Seven SLIC-signaling I/O pins per channel with programmable debouncing
• Two PCM Highways accessible by on-chip PCM Interface with Programmable time slot assignment and variable data rates from 128 kbit/s to 8 Mbit/s
• Easy to use 4-pin Serial Microcontroller Interface (SPI compatible) for read/write access
• Single supply voltage (5 V)
• Advanced low-power mixed-signal CMOS technology
• Two programmable tone generators per channel (DTMF possible)
• Level metering function for system tests and for analog input signal testing
• Advanced on-chip functions for device and system diagnostics and manufacturing test
– Five digital loops
– Four analog loops
• Support tools include:
– Hardware development board — STUT 2466
– QSICOS Coefficient Calculation and Register Configuration Software
• Standard P-MQFP-64 package -
