PEB2045N

The simens memory time switch PEB2045N is a monolithic CMOS circuit connecting any of 512 incoming PCM channels to any of 256 outgoing PCM channels.The on-chip connection memory is accessed via the 8-bit P interface.The PEB2045N is fabricated using the advanced CMOS technology from siemens and is mounted in a P-DIP-40 or a P-LCC-44 package.Inputs and outputs are TTL-compatible.The PEB2045N is pin and software compatible to the PEB2040.In addition,it includes the following features:(1)4096-kHz device clock.(2)4096-kbit/s PCM-data rate.(3)primary access configuration.(4)fast connection memory access.

The PEB2045N has fifteen features.(1)time/space switch for 2048-,4096- or 8192-kbit/s PCM systems.(2)switching of up to 512 incoming PCM channels to up to 256 outgoing PCM channels.(3)16-input kinds of modes of modes.(4)different kind of modes.(5)configurable for primary access and standard applications.(6)programmable clock shift with half clock step resolution for input and output primary access configuration.(7)configurable for a 4096- and 8192-kHz device clock.(8)tristate control signals for external drivers in primary access configuration.(9)tristate function for further expansion and tandem operation.(10)2048-kHz clock output in primary access configuration.(11)space switch mode.(12)8-bit P interface.(13)single+5V power supply.(14)advanced low power CMOS technology.(15)pin and software compatible to PEB2040.
