DETAILED DESCRIPTION
The DS21348 is a complete selectable E1 or T1 line interface unit (LIU) for short-haul and long-haul
applications. Throughout the data sheet, J1 is represented wherever T1 exists. Receive sensitivity adjusts
automatically to the incoming signal and can be programmed for 0dB to 12dB or 0dB to 43dB for E1
applications and 0dB to 30dB or 0dB to 36dB for T1 applications. The device can generate the necessary
G.703 E1 waveshapes in 75 or 120 applications and DSX-1 line build-outs or CSU line build-outs of
0dB, -7.5dB, -15dB, and -22.5dB for T1 applications. The crystal-less on-board jitter attenuator requires
only a 2.048MHz MCLK for both E1 and T1 applications (with the option of using a 1.544MHz MCLK
in T1 applications). The jitter attenuator FIFO is selectable to either 32 bits or 128 bits in depth and can
be placed in either the transmit or receive data paths. An X 2.048MHz output clock synthesized to RCLK
is available for use as a backplane system clock (where n = 1, 2, 4, or 8).
The DS21348 has diagnostic capabilities such as loopbacks and PRBS pattern generation/detection. 16-
bit loop-up and loop-down codes can be generated and detected. The device can be controlled through an
8-bit parallel muxed or nonmuxed port, serial port, or used in hardware mode. The device fully meets all
of the latest E1 and T1 specifications including ANSI T1.403-1999, ANSI T1.408, AT&T TR 62411,
ITU G.703, G.704, G.706, G.736, G.775, G.823, I.431, O.151, O.161, ETSI ETS 300 166, JTG.703,
JTI.431, JJ-20.1, TBR12, TBR13, and CTR4.
