4-Port LVDS and LVTTL-to-LVDS Repeaters
General Description
The MAX9169/MAX9170 low-jitter, low-voltage differen-
tial signaling LVDS/LVTTL-to-LVDS repeaters are ideal
for applications that require high-speed data or clock
distribution while minimizing power, space, and noise.
The devices accept a single LVDS (MAX9169) or LVTTL
(MAX9170) input and repeat the input at four LVDS out-
puts. Each differential output drives 100Ω, allowing
point-to-point distribution of signals on transmission
lines with 100Ω termination at the receiver input. The
MAX9169 and MAX9170 are pin compatible with the
SN65LVDS104 and SN65LVDS105, respectively, and
offer improved pulse-skew performance.
Ultra-low 150ps (max) pulse skew and 200ps
P-P
(max)
added deterministic jitter ensure reliable communica-
tion in high-speed links that are highly sensitive to tim-
ing error, especially those incorporating clock-and-data
recovery or serializers and deserializers. The high-
speed switching performance guarantees 630Mbps
data rate and less than 120ps channel-to-channel skew
over the 3.0V to 3.6V operating supply range.
Supply current is 30mA (max) for the MAX9169, and
25mA (max) for the MAX9170. LVDS inputs and outputs
conform to the ANSI EIA/TIA-644 standard. A fail-safe
feature on the MAX9169 sets the output high when the
input is undriven and open, terminated, or shorted. The
MAX9169/MAX9170 are offered in 16-pin TSSOP and
SO packages, and operate over an extended -40°C to
+85°C temperature range.
Refer to the MAX9130 data sheet for an LVDS line
receiver in an SC70 package.
