DS21455, DS21458 Quad T1/E1/J1 Transceivers

The DS21455 and DS21458 are quad monolithic devices featuring independent transceivers that CAN be software configured for T1, E1, or J1 operation. Each is composed of a line Interface unit (LIU), framer, HDLC controllers, and a TDM Backplane Interface and is controlled via an 8-bit parallel port configured for Intel or Motorola bus operations. The DS21455 is a direct replacement for the older DS21Q55 quad MCM device. The DS21458 in a smaller package (17mm CSBGA) and featuring an improved controller Interface is software compatible with the older DS21Q55.
*The JTAG function on the DS21455 DS21458 is a single controller for all four transceivers, unlike the DS21Q55 which has a JTAG controller-per-transceiver architecture.
