103 The power (TAVD1) pin for the transmit clock
synthesizer reference circuitry. TAVD1
should be connected to analog +5V.
104 The power (TAVD2) pin for the transmit clock
synthesizer oscillator. TAVD2 should be
connected to analog +5V.
102 The ground (TAVS1) pin for the transmit
clock synthesizer reference circuitry. TAVS1
should be connected to analog GND.
105 The ground (TAVS2) pin for the transmit
clock synthesizer oscillator. TAVS2 should
be connected to analog GND.
92 The transmit pad ring power (TXVD_AC)
supplies the TXD1+/- and TXD2+/- outputs.
TXVD_AC is physically isolated from the
other device power pins and should be a
clean, well decoupled +5 V supply to
minimize the noise coupled into the transmit
stream.
97 The transmit pad ring ground (TXVS_AC) is
the return path for the TXD1+/- and TXD2+/-
outputs. TXVS_AC is physically isolated
from the other device ground pins and
should be clean to minimize the noise
coupled into the transmit stream.
114 The power (R1AVD1) pin for the RXD1+/-
and ALOS1+/- PECL inputs and for channel
#1 receive clock and data recovery block
reference circuitry. R1AVD1 should be
connected to analog +5V.
