Signal Name:
LTDATA / LTDATB
Signal Description:
Low Speed (T1 or E1) Transmit Insert Port Serial Data Inputs
Signal Type:
Input
These two input signals allow data to be inserted in place of any of the 28 T1 data streams or into any of
the 16/21 E1 data streams (see Section 7.4). Data can be clocked into the device either on falling edges
(normal clock mode) or rising edges (inverted clock mode) of the associated LTCLK. This option is
controlled via the LTCLKI control bit in Master Control Register 2 (see Section 4.2). Also, the data can
be internally inverted before being multiplexed if enabled via the LTDATI control bit in Master Control
Register 2 (see Section 4.2). When the M13 / E13 multiplexer is disabled, then these inputs are ignored
and should be tied low.
Signal Name:
LTCLKA / LTCLKB
Signal Description:
Low Speed (T1 or E1) Transmit Insert Port Serial Clock Inputs
Signal Type:
Input
These two input signals are used to clock data into the device that will be inserted into one of the 28 T1
data streams or into one of the 16/21 E1 data streams (see Section 7.4). The T1 or E1 serial data streams
at the associated LTDAT signals can be clocked into the device either on falling edges (normal clock
mode) or rising edges (inverted clock mode) of LTCLKA/LTCLKB. This option is controlled via the
LTCLKI control bit in Master Control Register 2 (see Section 4.2). When the M13 / E13 multiplexer is
disabled, then these inputs are ignored and should be tied low.
Signal Name:
LTCCLK
Signal Description:
Low Speed (T1 or E1) Transmit Common Clock Input
Signal Type:
Input
If enabled via the LTCCEN in Master Control Register 1 (see Section 4.2), all 28 LTCLK or 16 LTCLK
signals are disabled and all the data at the 28 LTDAT or 16 LTDAT inputs (as well as the LTDATA and
LTDATB inputs) will be clocked into the device using the LTCCLK signal. In T3 mode, LTCCLK
would be a 1.544 MHz clock and in E3 mode, LTCCLK would be 2.048 MHz. If not used, this signal
should be tied low. If this signal is used, then all of the LTCLK signals should be tied low. This signal
can be internally inverted. This option is controlled via the LTCLKI control bit in Master Control
Register 2 (see Section 4.2).
