_________________________________________________PSB 7110
General Information
The ISAR PSB 7110, ISDN Data Access Controller forms an advanced solution for ISDN applications
communicating with remote ISDN as well as analog terminals. The ISAR is designed for applications on PC- or
workstation platforms, but can also be used in ISDN/analog combining terminals.
It integrates two data formatting units which support binary framing, HDLC and ASYNC, which is an asynchronous
data formatting according to ITU-T V.14. The data from the formatting units is than input data to a fax/modem
modulation or V.110 or transparent framing towards the IOM-2 timeslots.
The PSB 7110 operates on the IOM-2 interface in terminal mode (1.536 MHz DCL). It is also designed to operate on
line-card IOM-2 interfaces (4 MHz DCL).
The ISDN Data Access Controller uses external RAM to implement a 61 byte FIFO structure between the host and
the data formatting unit. The DSP program is also executed from external memory.
The PSB 7110 ISDN Data Access Controller is a 0.5 micron CMOS device offered in a thin quad-flat pack package.
It operates from a single 3.6V supply with the option to drive the interface lines by a 5V supply.
As ISAR Version 1.0 ensures firmware safety through its program download mechanism, a ROM version will be
following that will only require external SRAM of reduced size. This device will be ISAR Version 1.1.
Important Note:
Software Version #4
The ISAR V1.0 requires download software which is provided separately with the device.
This specification describes the functionality of the device with the software download version number 4.
