Quad LVDS Line Receiver with Flow-Through Pinout and "In-Path" Fail-Safe
General Description
The MAX9173 quad low-voltage differential signaling (LVDS) line receiver is ideal for applications requiring high data rates, low power, and low noise. The MAX9173 is guaranteed to receive data at speeds up to 500Mbps (250MHz) over controlled-impedance media of approximately 100. The transmission media can be printed circuit (PC) board traces or cables. The MAX9173 accepts four LVDS differential inputs and translates them to LVCMOS/LVTTL outputs. The MAX9173 inputs are high impedance and require an external termination resistor when used in a point-topoint connection. The device supports a wide common-mode input range of 0.05V to VCC - 0.05V, allowing for ground potential differences and common-mode noise between the driver and the receiver. A fail-safe feature sets the output high when the inputs are open, or when the inputs are undriven and shorted or undriven and parallel terminated. The EN and EN inputs control the high-impedance outputs. The enables are common to all four receivers. Inputs conform to the ANSI TIA/EIA-644 LVDS standard. The flow-through pinout simplifies board layout and reduces crosstalk by separating the LVDS inputs and LVCMOS/LVTTL outputs. The MAX9173 operates from a single 3.3V supply, and is specified for operation from -40C to +85C. Refer to the MAX9121/ MAX9122 data sheet for lower jitter quad LVDS receivers with parallel fail-safe. Refer to the MAX9123 data sheet for a quad LVDS line driver with flowthrough pinout. The device is available in 16-pin TSSOP, SO, and space-saving thin QFN packages.

Detailed Description
LVDS is a signaling method intended for point-to-point communication over a controlled-impedance medium as defined by the ANSI TIA/EIA-644 and IEEE 1596.3 standards. LVDS uses a lower voltage swing than other common communication standards, achieving higher data rates with reduced power consumption while reducing EMI and system susceptibility to noise. The MAX9173 is a 500Mbps, four-channel LVDS receiver intended for high-speed, point-to-point, low-power applications. Each channel accepts an LVDS input and
6
translates it to an LVTTL/LVCMOS output. The receiver is specified to detect differential signals as low as 100mV and as high as 1.2V within an input voltage range of 0 to VCC. The 250mV to 400mV differential output of an LVDS driver is nominally centered around a 1.2V offset. This offset, coupled with the receiver's 0 to VCC input voltage range, allows more than 1V shift in the signal (as seen by the receiver). This allows for a difference in ground references of the transmitter and the receiver, the common-mode effects of coupled noise, or both.

2.5A
Without fail-safe, differential noise at the input may switch the receiver and appear as data to the receiving system. An open input occurs when a cable and termination are disconnected. An undriven, terminated input occurs when a cable is disconnected with the termination still connected across the receiver inputs or when the driver of a receiver is in high impedance. An undriven, shorted input can occur due to a shorted cable.
5A
"In-Path" vs. "Parallel" Fail-Safe
The MAX9173 has in-path fail-safe that is compatible with in-path fail-safe receivers, such as the DS90LV048A. Refer to the MAX9121/MAX9122 data sheet for pin-compatible receivers with parallel fail-safe and lower jitter. Refer to the MAX9130 data sheet for a single LVDS receiver with parallel fail-safe in an SC70 package. The MAX9173 with in-path fail-safe is designed with a +45mV input offset voltage, a 2.5A current source between VCC and the noninverting input, and a 5A current sink between the inverting input and ground (Figure 1). If the differential input is open, the 2.5A current source pulls the input to approximately VCC 0.8V and the 5A current sink pulls the inverting input to ground, which drives the receiver output high. If the differential input is shorted or terminated with a typical value termination resistor, the +45mV offset drives the receiver output high. If the input is terminated and floating, the receiver output is driven high by the +45mV offset, and the 2:1 current sink to current source ratio (5A:2.5A) pulls the inputs to ground. This can be an advantage when switching between drivers on a multipoint bus because the change in common-mode voltage from ground to the typical driver offset voltage of 1.2V is not as much as the change from VCC to 1.2V (parallel fail-safe pulls the bus to VCC).

Applications Information
Differential Traces
Input trace characteristics affect the performance of the MAX9173. Use controlled-impedance board traces. For point-to-point connections, match the receiver input termination resistor to the differential characteristic impedance of the board traces. 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. Each channel's differential signals should be routed close to each other to cancel their external magnetic field. Maintain a constant distance between the differential traces to avoid discontinuities in differential impedance. Minimize the number of vias to further prevent impedance discontinuities.
Cables and Connectors
LVDS transmission media typically have controlled differential impedance of 100. Use cables and connectors that have matched differential impedance to minimize impedance discontinuities. Avoid the use of unbalanced cables such as 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.

ESD Protection
ESD-protection structures are incorporated on all pins to protect against electrostatic discharges encountered during handling and assembly. The receiver inputs of the MAX9173 have 7.0kV of protection against static electricity (per Human Body Model). Figure 6a shows the Human Body Model, and Figure 6b shows the current waveform it generates when discharged into a low-impedance load. This model con-

Termination
The MAX9173 requires an external termination resistor. The termination resistor should match the differential impedance of the transmission line. Termination resistance values may range between 90 to 132, depending on the characteristic impedance of the transmission medium. When using the MAX9173, minimize the distance between the input termination resistors and the MAX9173 receiver inputs. Use 1% surface-mount resistors. inputs should be separated by 180 from the LVTTL/LVCMOS outputs to reduce crosstalk. For LVDS applications, a four-layer PC board that provides separate layers of power, ground, LVDS inputs, and output signals is recommended. When using the QFN package, solder the exposed pad (EP) to the ground plane using an array of vias for proper heat dissipation.
Board Layout
In general, separate the LVDS inputs from single-ended outputs to reduce crosstalk. Take special care when routing traces with the QFN package. Ideally, the LVDS TRANSISTOR COUNT: 1462 PROCESS: CMOS
