PEB20570F V2.3
The DELIC and VIP chipset realizes multiple ISDN S/T and UPN interfaces together with
controller functionality typically needed in PBX or Central Office systems. This
functionality comprises voice channel handling, signaling control, layer-1 control, and
even signal processing tasks.
Moreover it provides a programmable master/slave clock generator with 2 PLLs, an
universal µP interface and a DMA interface.
The controller part, DELIC, is available in two different versions:
• DELIC-LC (PEB 20570) is a line card controller providing voice channel switching,
multiple HDLC and layer-1 control for up to three VIPs (24 ISDN channels). Other
transceiver ICs (32 analog or 16 digital channels) may additionally be connected via
IOM-2/GCI interface.
• DELIC-PB (PEB 20571) additionally provides a programmable telecom DSP
including program and data RAM. This DSP can be used for layer-1 control, protocol
support and signal processing. The flexibility gained by the programmability allows
Infineon to offer different application specific solutions with the same silicon just by
software configuration.
A configuration tool assists the user in finding a valid system configuration. Even more
customer specific DSP-routines can be integrated with the assistance of Infineon.
The transceiver part, VIP, is available in two different versions:
• VIP PEB 20590 is the first (8 channel) ISDN transceiver that implements multiple UPN
and S/T interfaces within one device. The user can decide by programming in which
mode a desired channel shall work.
A total of 8 channels are provided for layer-1 subscriber or trunk line characteristic.
The VIP is programmed by the DELIC via the IOM-2000 interface. VIP’s eight
channels are programmable in the following maximum partitioning between UPN and
S/T channels:
