DS2152中文资料增强型T1单芯片收发器数据手册ADI规格书

描述 Description

The DS2152 is a second-generation line interface unit for T1 lines. It is pin- and software-compatible with the first-generation DS2151Q and function- and pin-compatible with the DS2154, its E1 counterpart. The DS2152 retains all features of the DS2151Q, 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 DS2152 meets T1 specifications, including ANSI T1 403-1995, ANSI T1.231-1993, AT&T TR 6241 (12-90), AT&T TR54016, and ITU G.703, G.704 G.706, G.823, and 1.431, that network to central office interfaces. Via the parallel port, the user can quickly access the internal 8-bit internal registers to configure the DS2152 to the application under processor control.
