MAXIM MAX9113EKA

19-1803; Rev 3; 3/09
Single/Dual LVDS Line Receivers with
Ultra-Low Pulse Skew in SOT23
Features
The MAX9111/MAX9113 single/dual low-voltage differential signaling (LVDS) receivers are designed for highspeed applications requiring minimum power
consumption, space, and noise. Both devices support
switching rates exceeding 500Mbps while operating from
a single +3.3V supply, and feature ultra-low 300ps (max)
pulse skew required for high-resolution imaging applications such as laser printers and digital copiers.
The MAX9111 is a single LVDS receiver, and the
MAX9113 is a dual LVDS receiver.
Both devices conform to the EIA/TIA-644 LVDS standard
and convert LVDS to LVTTL/CMOS-compatible outputs.
A fail-safe feature sets the outputs high when the inputs
are undriven and open, terminated, or shorted. The
MAX9111/MAX9113 are available in space-saving 8-pin
SOT23 and SO packages. Refer to the MAX9110/
MAX9112 data sheet for single/dual LVDS line drivers.

_______________Detailed Description
LVDS Inputs
The MAX9111/MAX9113 feature LVDS inputs for interfacing high-speed digital circuitry. The LVDS interface
standard is a signaling method intended for point-topoint communication over a controlled impedance
media, as defined by the ANSI/EIA/TIA-644 standards.
The technology uses low-voltage signals to achieve fast
transition times, minimize power dissipation, and noise
immunity. Receivers such as the MAX9111/MAX9113
convert LVDS signals to CMOS/LVTTL signals at rates
in excess of 500Mbps. The devices are capable of
detecting differential signals as low as 100mV and as
high as 1V within a 0V to 2.4V input voltage range . The
LVDS standard specifies an input voltage range of 0 to
2.4V referenced to ground.
Fail-Safe
The fail-safe feature sets the output to a high state
when the inputs are undriven and open, terminated, or
shorted. When using one channel in the MAX9113,
leave the unused channel open. The fail-safe feature is
not guaranteed to be operational above +85°C.
Receiver Inverting Differential Input
Receiver Noninverting Differential Input
No Connection. Not internally connected.
ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against electrostatic
discharges encountered during handling and assembly.
The receiver inputs of the MAX9111/MAX9113 have extra
protection against static electricity. Maxim’s engineers
have developed state-of-the-art structures to protect
these pins against ESD of ±11kV without damage. The
ESD structures withstand high ESD in all states: normal
operation, shutdown, and powered down.
ESD protection can be tested in various ways; the
receiver inputs of this product family are characterized
for protection to the limit of ±11kV using the Human
Body Model.
Human Body Model
Figure 3a shows the Human Body Model, and Figure
3b shows the current waveform it generates when discharged into a low impedance. This model consists of a
100pF capacitor charged to the ESD voltage of interest,
which is then discharged into the test device through a
1.5kΩ resistor.

__________ Applications Information
Supply Bypassing
Bypass VCC with high-frequency surface-mount ceramic 0.1µF and 0.001µF capacitors in parallel, as close to
the device as possible, with the 0.001µF valued capacitor the closest to the device. For additional supply
bypassing, place a 10µF tantalum or ceramic capacitor
at the point where power enters the circuit board.
Differential Traces
Output trace characteristics affect the performance of
the MAX9111/MAX9113. Use controlled impedance
traces to match trace impedance to both transmission
medium impedance and the termination resistor.
Eliminate reflections and ensure that noise couples as
common mode by running the differential traces close
together. Reduce skew by matching the electrical
length of the traces. Excessive skew can result in a
degradation of magnetic field cancellation.
Maintain the distance between the differential traces to
avoid discontinuities in differential impedance. Avoid
90° turns and minimize the number of vias to further
prevent impedance discontinuities.

CURRENT WAVEFORM
Figure 3b. Human Body Current Waveform
Termination
The MAX9111/MAX9113 input differential voltage
depends on the driver current and termination resistance. Refer to the MAX9110/MAX9112 differential driver data sheet for this information.
Minimize the distance between the termination resistor
and receiver inputs. Use a single 1% to 2% surfacemount resistor across the receiver inputs.
Board Layout
For LVDS applications, a four-layer PCB that provides
separate power, ground, LVDS signals, and input signals is recommended. Isolate the input and LVDS signals from each other to prevent coupling. For best
results, separate the input and LVDS signal planes with
the power and ground planes.
Cables and Connectors
Transmission media should have a differential characteristic impedance of about 100Ω. Use cables and connectors that have matched 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 canceling effects. Balanced cables
tend to pick up noise as common mode, which is
rejected by the LVDS receiver.
