Master Clock Input. An independent and free-running 2.048 or 1.544 MHz clock input
generates the internal reference clocks for all Receivers. On Loss of Signal (LOS), the
LXT336 derives RCLKx from this master clock. With MCLK asserted High, the LXT336
disables the PLL clock recovery circuits. The Receiver then feeds RPOSx and RNEGx to
an internal XOR gate that performs logically exclusive ORs for both data signals and
connects this output to RCLKx for external clock recovery. In this mode, the LXT336
operates as a data recovery circuit. With MCLK asserted Low, the LXT336 powers down
its clock and data recovery circuits and switches the output pins RCLKx, RPOSx and
RNEGx to tri-state mode.
Clocked Data/Clock Recovery
Clock Input - Port 0. All CLKIx pins are identical. Connect to MCLK for unipolar operation
mode (single rail plus clock). For bipolar operation mode (dual rail plus clock), CLK0
should be connected to ground.
Ground.
Unipolar-Bipolar Select Input–Port 0. All UBSx pins are identical. If this pin is asserted
High for more than 16 CLKI cycles, the LXT336 switches to unipolar mode. HDB3 or AMI
decoder mode is selected by the MODE pin.
The device is set to bipolar mode when this pin is asserted Low.
Clock Input - Port 1. See CLKI0, pin 2.
