DS2154
Enhanced E1 Single Chip Transceiver
|
Status
Active: In Production.
Description
The DS2154 is a second-generation line interface unit for E1 lines. It is pin- and software-compatible with the first-generation DS2153Q and function- and pin-compatible with the DS2152, its T1 counterpart. The DS2154 retains all features of the DS2153Q adding crystalless jitter attenuation, additional hardware signaling, a full HDLC controller for the FDL layer with 16-byte buffers, and the option for nonmultiplexed bus operation.
The DS2154 meets E1 specifications, including ETS 300 011, 300 233, 300 166, TBR 12, and TBR 13 and ITU G.703, G.704, G.706, G.823, and I.431.
Through the parallel port, the user can quickly access the 8-bit internal registers and configure the DS2154 to the application under processor control.
