Detailed Description
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
feature ultra-low 80psP-P deterministic jitter (max) that
ensures reliable operation in high-speed links that are
highly sensitive to timing error.
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 inputs tolerate undershoot of -1V and
overshoot of VCC + 1V. The MAX9174/MAX9175 are
available in 10-pin MAX and 10-lead thin QFN pack-
ages, and operate from a single +3.3V supply over the
-40°C to +85°C temperature range.
Current-Mode LVDS Outputs
The LVDS outputs use a current-steering configuration.
This approach results in less ground bounce and less
output ringing, enhancing noise margin and system
speed performance.
A differential output voltage is produced by steering
current through the parallel combination of the integrat-
ed differential output resistor and transmission line
impedance/termination resistor. When driving a 100
termination resistor, a differential voltage of 250mV to
475mV is produced. For loads greater than 100, the
output voltage is larger, and for loads less than 100,
the output voltage is smaller. See the Differential Output
Voltage vs. Load Resistance curve in Typical Operating
Characteristics for more information. The outputs are
short-circuit current limited for single-ended and differ-
ential shorts.
MAX9174 Input Fail-Safe
The fail-safe feature of the MAX9174 sets the outputs
high when the differential input is:
Open
Undriven and shorted
Undriven and terminated
Without a fail-safe circuit, when the input is undriven,
noise at the input may switch the outputs and it may
appear to the system that data is being sent. Open or
undriven terminated input conditions can occur when a
cable is disconnected or cut, or when a driver output is
in high impedance. A shorted input can occur because
of a cable failure.
