Type
Power and ground pairs for ESD structure.
Received Parallel Data Output. RX<0> is the least significant bit and is
received first. When DIN± lose input data, all RX pins will be held HIGH.
Comma detect. This pin is active HIGH. When asserted, it indicates the
detection of comma character (0011111XXX). It is active only when EN_CEDT
is enabled.
Power and ground pair for the front-end of the receiver section.
High-speed serial data input. Serial data input is received when
EWRAP is disabled.
Power and ground pair for ESD structure.
Power and ground pair for analog circuits of the receiver section.
Power supply to line driver circuits. Ground supply is from pin 64.
High-speed serial data output. These pins are active when EWRAP is disabled
and are held static at logic 1 when EWRAP is enable.
Power and ground pair for high-speed transmit logic in the parallel-to-serial
section.
