Control
RPD - Receiver Power Down, LQFP Pin 10, BGA Pin E1
When RPD is Low, the complete receive path for all ports is powered down the output pins
RPOS, RNEG and RCLK are switched to the high impedance state.
TXOE - Transmitter Output Enable, LQFP Pin 114, BGA Pin E14
When TXOE is asserted Low, all of the TX drivers are forced to a high impedance state in
1
μ
S (max). All other internal circuitry remains active.
RPS - Receiver Polarity Select, LQFP Pin 115, BGA Pin E13
This pin is used to set the polarity of RPOS/RNEG. When RPS is High, RPOS/RNEG has an
active high output polarity. When RPS is low, RPOS/RNEG have an active Low polarity.
LOOP0 - Loopback Mode Select Port #0, LQFP Pin 21, BGA Pin G2
This pin selects the loopback mode for LIU transceiver 0. The mode is selected as follows:
No Loopback - LOOP0 is left open (unconnected)
Local Loopback - LOOP0 is tied High. In this mode, data transmitted on TTIP0 and TRING0
is looped back into port 0’s receiver and output on RPOS0 and RNEG0. Data present on RTIP0
and RRING0 is ignored.
Remote Loopback - LOOP0 is tied Low. In this mode, data received on RTIP0 and RRING0 is
looped back for retransmission on TTIP0 and TRING0. Data on TPOS0 and TNEG0 is
ignored.
LOOP1 - Loopback Mode Select Port #1, LQFP Pin 22, BGA Pin H3
LOOP2 - Loopback Mode Select Port #2, LQFP Pin 23, BGA Pin H2
LOOP3 - Loopback Mode Select Port #3, LQFP Pin 24, BGA Pin J4
LOOP4 - Loopback Mode Select Port #4, LQFP Pin 25, BGA Pin J3
LOOP5 - Loopback Mode Select Port #5, LQFP Pin 26, BGA Pin J2
LOOP6 - Loopback Mode Select Port #6, LQFP Pin 27, BGA Pin J1
LOOP7 - Loopback Mode Select Port #7, LQFP Pin 28, BGA Pin K1
