Product Summary

The PM7341-PI is a monolithic integrated circuit that implements the ATM Forum Inverse Multiplexing for ATM (IMA 1.1) protocol with backward compatibility to IMA 1.0 and the Transmission Convergence (TC) layer function. The PM7341-PI has two line side interface modes that determine the total number of physical links supported: the Scalable Bandwidth Interconnect (SBI) bus interface mode and the Clock and Data interface mode.
