MAX9174/MAX9175
When the input is driven with a differential signal of |VID|
= 50mV to 1.2V within a voltage range of 0 to 2.4V, the
fail-safe circuit is not activated. If the input is open,
undriven and shorted, or undriven and terminated, an
internal resistor in the fail-safe circuit pulls the input
above VCC - 0.3V, activating the fail-safe circuit and
forcing the outputs high (Figure 1).
Overshoot and Undershoot Voltage
Protection
The MAX9174/MAX9175 are designed to protect the
power-down inputs (PD0 and PD1) against latchup due
to transient overshoot and undershoot voltage. If the
input voltage goes above VCC or below GND by up to
1V, an internal circuit limits input current to 1.5mA.
Applications Information
Power-Supply Bypassing
Bypass the VCC pin with high-frequency surface-mount
ceramic 0.1F and 0.001F capacitors in parallel as
close to the device as possible, with the smaller valued
capacitor closest to VCC.
Differential Traces
Input and output trace characteristics affect the perfor-
mance of the MAX9174/MAX9175. Use controlled-
impedance differential traces (100 typ). To reduce
radiated noise and ensure that noise couples as com-
mon mode, route the differential input and output sig-
nals within a pair close together. Reduce skew by
matching the electrical length of the two signal paths
that make up the differential pair. Excessive skew can
result in a degradation of magnetic field cancellation.
Maintain a constant distance between the differential
traces to avoid discontinuities in differential impedance.
Minimize the number of vias to further prevent imped-
ance discontinuities.
Cables and Connectors
Interconnect for LVDS typically has a controlled differ-
ential impedance of 100. Use cables and connectors
that have matched differential impedance to minimize
impedance discontinuities.
Avoid the use of unbalanced cables such as ribbon or
simple coaxial cable. Balanced cables such as twisted
pair offer superior signal quality and tend to generate
less EMI due to magnetic field canceling effects.
Balanced cables pick up noise as common mode,
which is rejected by the LVDS receiver.
Termination
The MAX9174/MAX9175 require external input and out-
put termination resistors. For LVDS, connect an input
termination resistor across the differential input and at
the far end of the interconnect driven by the LVDS out-
puts. Place the input termination resistor as close to the
receiver input as possible. Termination resistors should
match the differential impedance of the transmission
line. Use 1% surface-mount resistors.
