PLL filter capacitor should be connected from pins
79 and 80 to pins 1 and 2 (typical value = 0.01 F).
See Figures 18, 19, 20, and 21.
PLL filter capacitor should be connected from pins

See Figures 18, 19, 20, and 21.
A 53.125 MHz clock supplied by the host system.
CLKIN is used by the internal PLL to acquire frequency
lock when the -LCKREF input is brought low.
Indicates the detection of a comma character
(K28.5 of positive disparity). It is only active when
EN_CDET is high.
High speed serial data inputs, selected when EWRAP
is set low. An optional cable equalizer may also be
enabled, see EQEN.
