General Description
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.
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.

NAME FUNCTION
__________ Applications Information
Supply Bypassing
Bypass VCCwith 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.
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.
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.
