670MHz LVDS-to-LVDS and Anything-to-LVDS
1:2 Splitters
General Description
Features
The MAX9174/MAX9175 are 670MHz, low-jitter, low-
skew 1:2 splitters ideal for protection switching, loop-
back, and clock and signal distribution. The devices

♦ +3.3V Supply
♦ LVDS Fail-Safe Inputs (MAX9174)
ensures reliable operation in high-speed links that are
highly sensitive to timing errors.
♦ Anything Input (MAX9175) Accepts Differential
The MAX9174 has a fail-safe LVDS input and LVDS out-
puts. The MAX9175 has an anything differential input
(CML/LVDS/LVPECL) and LVDS outputs. The outputs
can be put into high impedance using the power-down
inputs. The MAX9174 features a fail-safe circuit that dri-
ves the outputs high when the input is open, undriven
and shorted, or undriven and terminated. The MAX9175
has a bias circuit that forces the outputs high when the
input is open. The power-down inputs are compatible
with standard LVTTL/LVCMOS logic. The power-down

+ 1V. The MAX9174/MAX9175 are available in 10-pin
µMAX and 10-lead thin QFN with exposed pad pack-
ages, and operate from a single +3.3V supply over the
-40°C to +85°C temperature range.
