Two Channel Codec Filter for Terminal Applications SICOFI®2-TE
Four Channel Codec Filter for Terminal Applications SICOFI®4-TE
Overview
The Signal Processing Codec Filter for terminal applications PSB 2132/4 SICOFI2/4-TE is a special derivative of the SIEMENS programmable codec-filter- IC family designed for terminal applications featuring two or four POTS interfaces.
It can be directly connected to the IOM-2 interface in terminal mode running at 1.536 MHz clock rate. PCM data is transfered using the bit clock signal at 768 kHz.
Programming of internal registers is done via the serial microcontroller interface.Features
• Single chip programmable CODEC and FILTER to
handle two or four POTS interfaces
• IOM-2 compatible interface (1.536 MHz DCL, 768
kHz Bit clock)
• Internal communication between POTS interfaces
• Programmable I/O lines for signaling information per
channel
• Programmable ring generator output
• Two programmable tone generators per channel
• Serial microcontroller interface
• Digital signal processing technique
• High analog driving capability (300 Ω) for direct
driving of transformers
• Programmable digital filters to adapt the transmission behaviour especially for
– AC impedance matching
– transhybrid balancing
– frequency response
– gain
– A/µ-law conversion
• Single 5 V power supply
• Low power 0.9 µm analog CMOS technology
• Advanced test capabilities
• P-MQFP-64 package -
