PM7389 - Frame Engine and Datalink Manager

Download the PM7389 datasheet PDF. This datasheet also covers the PM7389_PMC variant, as both devices belong to the same frame engine and datalink manager family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • Single-chip multi-channel packet processor supporting a maximum aggregate bandwidth of 156 Mbit/s for line rate throughput transfers of packet sizes from 40 to 9.6 Kbytes, for up to an aggregate of 84 T1s, 63 E1s, or 3 DS-3s.
  • Provides simultaneous support of PPP, Frame Relay, Multilink-PPP and Multilink-Frame Relay protocols. Alternative protocols supported via HDLC termination and full packet store of the data within the HDLC structure.
  • Support for 3 egress fragmen.
