T1/E1/J1 Single-Chip Transceiver TDM/UTOPIA II Interface

Maxim Integrated 

DS2156

Signal Name:

RPOSO

Signal Description:

Receive Positive-Data Output

Signal Type:

Output

Updated on the rising edge of RCLKO with bipolar data out of the line interface. This pin is normally connected to

RPOSI.

Signal Name:

RNEGO

Signal Description:

Receive Negative-Data Output

Signal Type:

Output

Updated on the rising edge of RCLKO with the bipolar data out of the line interface. This pin is normally

connected to RPOSI.

Signal Name:

RCLKO

Signal Description:

Receive Clock Output

Signal Type:

Output

Buffered recovered clock from the network. This pin is normally connected 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 connected together for an NRZ interface. Can be internally connected to RPOSO by connecting 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 connected together for an NRZ interface. Can be internally connected to RNEGO by connecting 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 connected to RCLKO. Can be

internally connected to RCLKO by connecting the LIUC pin high.
