APPLICATION NOTE 328
DS2141A Creating a DS/ESF Channel Service Unit

Abstract: DS2141A can be used for creating a DS/ESF Channel Service Unit. This application note has the
adequate information and schematic on how to use this device DS2141A to create this Channel Service Unit.

Notes:

1. This application uses "looped" timing (i.e., RCLK is tied to TCLK)
2. MHz clock source is used as a transmit clock if no signal exists on the receive side; if the DS2291
declares a carrier loss, then the source of the TCLK will be switched from the recovered clock to the
locally accurate 1.544 MHz sou……
