0 dB, -7.5 dB, -15 dB, and -22.5 dB for T1 applications. The crystal-less onboard jitter attenuator
requires only a 2.048 MHz MCLK for both E1 and T1 applications (with the option of using a 1.544 MHz
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 n X 2.048 MHz 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 via an 8-bit
parallel MUX’d or non-MUX’d 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.
