Receive Clock Output–Port 3. All RCLKx pins are identical. This pin provides the recovered
clock from the signal received at RTIPx and RRINGx. In loss of signal conditions the LXT334
connects MCLK to this pin through internal circuitry.
Asserting the MCLK pin High disables the clock recovery circuit and internally connects RPOSx
and RNEGx to an XOR that is fed to the RCLKx output for external clock recovery applications.
Receive Negative Data/Violation Indication Output–Port 2.
See RNEG3/BPV3, pin 49; RPOS3/RDATA3, pin 50.
Receive Positive Data/Receive Data Output–Port 2. (In Data Recovery Mode, this signal is
active Low.) See RPOS3/RDATA3, pin 50; RNEG3/BPV3, pin 49.
Receive Clock Output–Port 2. See RCLK3, pin 51.
Loopback Mode Select Input–Port 3. All LOOPx pins are identical. Driving this pin Low selects
Remote Digital Loopback which causes the LXT334 to ignore any incoming data on TPOSx and
TNEGx. It then retransmits data from RTIPx and RRINGx back to TTIPx and TRINGx at the
RCLKx rate.
Driving this pin High selects Local Loopback which causes the LXT334 to ignore data received on
RTIPx and RRINGx and loop data internally from TTIPx and TRINGx back around to the receive
inputs.
Leaving this pin open selects normal operation mode.
Loopback Mode Select Input–Port 2. See LOOP3, pin 55.
Loopback Mode Select Input–Port 1. See LOOP3, pin 55.
Loopback Mode Select Input–Port 0. See LOOP3, pin 55.
Receive Negative Data/Bipolar Violation Indication Output–Port 1.
See RNEG3/BPV3, pin 49; RPOS3/RDATA3, pin 50.
Receive Positive Data/Receive Data Output–Port 1. (In Data Recovery Mode, this signal is
active Low.) See RPOS3/RDATA3, pin 50; RNEG3/BPV3, pin 49.
Receive Clock Output–Port 1. See RCLK3, pin 51.
Receive Negative Data/Bipolar Violation Indication Output–Port 0. See RNEG3/BPV3, pin
49; RPOS3/RDATA3, pin 50.
Receive Positive Data/Receive Data Output–Port 0. (In Data Recovery Mode, this signal is
active Low.) See RPOS3/RDATA3, pin 50; RNEG3/BPV3, pin 49.
Receive Clock Output–Port 0. See RCLK3, pin 51.
