Signal Name:
RPOS
Signal Description:
Receive Positive Data Input
Signal Type:
Input
Sampled on the falling edge of RCLK for data to be clocked through the receive side framer. RPOS and
RNEG can be tied together for an NRZ interface. Connecting RPOS to RNEG disables the bipolar
violation monitoring circuitry.
Signal Name:
RNEG
Signal Description:
Receive Negative Data Input
Signal Type:
Input
Sampled on the falling edge of RCLK for data to be clocked through the receive side framer. RPOS and
RNEG can be tied together for an NRZ interface. Connecting RPOS to RNEG disables the bipolar
violation monitoring circuitry.
Signal Name:
RCLK
Signal Description:
Receive Clock Input
Signal Type:
Input
Clock used to clock data through the receive side framer.
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.
Signal Name:
FMS
Signal Description:
Framer Mode Select
Signal Type:
Input
Set low to select DS21Q42 feature set. Set high to select DS21Q41 emulation. FMS is tied to ground for
the DS21FF42/DS21FT42.
Signal Name:
MUX
Signal Description:
Bus Operation
Signal Type:
Input
Set low to select non–multiplexed bus operation. Set high to select multiplexed bus operation.
Signal Name:
D0 to D7/ AD0 to AD7
Signal Description:
Data Bus or Address/Data Bus
Signal Type:
Input /Output
In non–multiplexed bus operation (MUX = 0), serves as the data bus. In multiplexed bus operation
(MUX = 1), serves as a 8–bit multiplexed address / data bus.
