S/UNI-IMA-4 Telecom Standard Product Data Sheet
Released
o
Serial link interface supports both independent transmit clock (ITC) and common
transmit clock (CTC) options.
Sꢀ Interfaces to a 1M x 16 SDRAM (16 Mbits of storage for 282 msec of T1, 226 msec of
E1 differential delay tolerance) through a 16-bit SDRAM interface. Note that other
larger SDRAM sizes can also be supported to support future market availability.
Sꢀ Provides a 16-bit microprocessor bus interface for configuration and Link and Unit
Management.
Sꢀ ATM receive interface supports 8- and 16-bit UTOPIA L2 or Any-PHY cell interfaces at
clock rates up to 52 MHz.
o
Any-PHY receive slave appears as single device. The PHY-ID of each cell is
identified in the in-band address.
o
o
UTOPIA L2 receive slave appears as a 4 port multi-PHY.
UTOPIA L2 receive slave can also appear as a single port with the logical port
provided as a prepend or in the HEC/UDF field.
Sꢀ ATM transmit interface supports 8- and 16-bit UTOPIA L2 and Any-PHY cell interfaces
at clock rates up to 52 MHz.
o
o
o
Each link configured for cell delineation or each IMA group appears as a PHY port on
the Any-PHY and UTOPIA L2 bus.
Any-PHY transmit slave appears as a 4-port multi-PHY. The PHY-ID of each cell is
identified in the in-band address.
UTOPIA L2 transmit slave appears as a 4-port multi-PHY.
Loopback and Diagnostic Features
Sꢀ Supports UTOPIA L2 / Any-PHY Loopback (global loopback– where all cells received
on the UTOPIA L2 / Any-PHY interface are looped back out).
Sꢀ Supports Line Side Loopback (global loopback– where all data received on the line side
is looped back out).
Sꢀ Supports the capability to trace ICP cells for any group.
Software
Sꢀ The S/UNI-IMA device driver, written in ANSI C, provides a well-defined Application
Programming Interface (API) for use by application software. Low level utility functions
are also provided for diagnostics and debugging purposes. Software wrappers are used
for RTOS-related functions making the S/UNI-IMA device driver portable to any Real
Time Operating System (RTOS) and hardware environment. The S/UNI-IMA device
driver is compatible across the S/UNI-IMA family of devices.
Packaging
Sꢀ Implemented in low power, 0.18 micron, 1.8V CMOS technology with TTL compatible
inputs and outputs.
Sꢀ Provides a standard 5-pin P1149 JTAG port.
Sꢀ 324 ball PBGA, 23mm x 23mm.
