RXLBQ,
/RXLBQ
Receiver loopback CML compatible output pair. When the SY58627L is in local
Loopback mode (LBSEL = 1), RXLBQ output is directed from TXLBIN (no
equalization). When the SY58627L is in normal mode (LBSEL = LOW) and the
RXLBQ output is not required, disable the RXLBQ output (/RXLBEN = HIGH) to
minimize switching noise. This differential output pair is optimized to drive 400mV
PK
swing into a 50
load (100
across the pair). The RXLBQ output pair includes 50
internal source termination resistors.

RXQ,
/RXQ
Receiver differential CML compatible output pair: This CML-compatible output pair is
the equalized signal seen at the RXIN input pair and is optimized to drive 400mV
PK
swing into a 50
load (100
across the pair). The RXQ output pair includes 50
internal source termination resistors. When the SY58627L is in Loopback mode
(LBSEL = HIGH), then the RXQ output signal is directed from the unequalized
TXLBIN input.

VTTOUT
Output termination center-tap: Each side of the RXQ differential output pair
terminates to the VTTOUT
pin through 50
. The VTTOUT pin provides a center-tap
to the output termination network for maximum interface flexibility, and DC-offset
capability. Please refer to the “CML Output Interface Applications” section for more
details.

EQ2( MSB)
EQ1
EQ0
TTL/CMOS (or VTH controlled) compatible, 3-bit control interface. There are four
levels of equalization, as shown in the “Equalization Select Truth Table.” When the
MSB is logic HIGH, the RXQ output pair will not include any equalization.
000 = lowest equalization setting
001 = medium equalization setting
010 = medium-high equalization setting
011 = highest equalization setting
1XX = equalization bypass

VCC
Positive Power Supply: Connect to +3.3V power supply. Bypass with 0.1μF//0.01μF
low ESR capacitors as close to VCC pins as possible.
