Signal Name:
8MCLK
Signal Description:
8 MHz Clock
Signal Type:
Output
An 8.192MHz clock output that is referenced to the clock that is output at the RCLK pin.
Signal Name:
RPOSO
Signal Description:
Receive Positive Data Input
Signal Type:
Output
Updated on the rising edge of RCLKO with bipolar data out of the line interface. This pin is normally
tied to RPOSI.
Signal Name:
RNEGO
Signal Description:
Receive Negative Data Input
Signal Type:
Output
Updated on the rising edge of RCLKO with the bipolar data out of the line interface. This pin is normally
tied to RPOSI.
Signal Name:
RCLKO
Signal Description:
Receive Clock Output
Signal Type:
Output
Buffered recovered clock from the T1 line. This pin is normally tied to RCLKI.
Signal Name:
RPOSI
Signal Description:
Receive Positive Data Input
Signal Type:
Input
Sampled on the falling edge of RCLKI for data to be clocked through the receive side framer. RPOSI and
RNEGI can be tied together for a NRZ interface. Can be internally connected to RPOSO by tying the
LIUC pin high.
Signal Name:
RNEGI
Signal Description:
Receive Negative Data Input
Signal Type:
Input
Sampled on the falling edge of RCLKI for data to be clocked through the receive side framer. RPOSI and
RNEGI can be tied together for a NRZ interface. Can be internally connected to RNEGO by tying the
LIUC pin high.
Signal Name:
RCLKI
Signal Description:
Receive Clock Input
Signal Type:
Input
Clock used to clock data through the receive side framer. This pin is normally tied to RCLKO. Can be
internally connected to RCLKO by tying the LIUC pin high.
4.1.3 Parallel Control Port Pins
Signal Name:
INT*
Signal Description:
Interrupt
Signal Type:
Output
Flags host controller during conditions and change of conditions defined in the Status Registers 1 and 2
and the HDLC Status Register. Active low, open drain output
