Function
Transmit Line 2 Monitor
Analog input from the external transmit
transformer (XL2). This pin must be connected
otherwise the XL2 pin could be set in a high
impedance state. If digital inputs are selected via
LIM1.DRS = 1 this input has to be switched to
V
Positive Power Supply for analog transmitter
Transmit Clock
Transmit clock frequency: 1544 kHz. Derived from
the XTAL3 or RCLK or internally generated.
If LIM1.EFSC is set high an 8-kHz Frame
Synchronization Pulse is output via this pin. The
synchronization pulse is active high for one 2 MHz
cycle (pulse width = 488 ns) and is derived from
the clock supplied by pin XTAL1.
Not connected. For further application this pin
should be connected to
8-kHz Frame Synchronization Pulse is active
low for one 2 MHz cycle (pulse width = 488 ns)
and is derived from the clock supplied by pin
XTAL1.
System Clock 16.384 MHz
System Clock 12.352 MHz only if a crystal or an
oscillator is connected to XTAL3/4.
System Clock 8.192 MHz
The frequency is derived from the clock supplied
by pin XTAL1.
System Clock Output
Output frequencies are: 2.048 MHz or 4.096 MHz
inverted or non-inverted. The frequency and
sense on this pin is selectable via LIM0.SCL1/0
and is derived from the clock supplied by pin
XTAL1.
