High speed data paths and flow-through pinout minimize internal device jitter and simplify board layout, while pre-emphasis overcomes ISI jitter effects from lossy backplanes and cables. The differential inputs interface to LVDS, and Bus LVDS signals such as those on TI's 10-, 16-, and 18- bit Bus LVDS SerDes, as well as CML and LVPECL. The differential inputs and outputs of the DS15BR400 are internally terminated with 100Ω resistors to improve performance and minimize board space. The DS15BR401 does not have input termination resistors. The repeater function is especially useful for boosting signals for longer distance transmission over lossy cables and backplanes. 1 2 • • • • • • • DC to 2 Gbps Low Jitter, High Noise Immunity, Low Power Operation 6 dB of Pre-emphasis Drives Lossy Backplanes and Cables LVDS/CML/LVPECL Compatible Input, LVDS Output On-chip 100 Ω output termination, optional 100 Ω Input Termination 15 kV ESD Protection on LVDS Inputs and Outputs Single 3.3V Supply Industrial -40 to +85°C Temperature Range Space Saving WQFN-32 or TQFP-48 Packages APPLICATIONS • • • Cable Extension Applications Signal Repeating and Buffering Digital Routers The DS15BR400/DS15BR401 are powered from a single 3.3V supply and consume 578 mW (typ).

The inputs have a 100Ω resistor across the differential pair, placing the receiver termination as close as possible to the input stage of the device. The LVDS outputs also contain an integrated 100Ω ohm termination resistor, this resistor is used to minimize the output return loss and does not take the place of the 100 ohm termination at the inputs to the receiving device. The integrated terminations improve signal integrity and decrease the external component count resulting in space savings. The DS15BR401 has 100Ω output terminations only. OUTPUT CHARACTERISTICS The output characteristics of the DS15BRB400/DS15BR401 have been optimized for point-to-point backplane and cable applications, and are not intended for multipoint or multidrop signaling. POWERDOWN MODE The PWDN input activates a hardware powerdown mode. When the powerdown mode is active (PWDN=L), all input and output buffers and internal bias circuitry are powered off. When exiting powerdown mode, there is a delay associated with turning on bandgap references and input/output buffer circuits as indicated in the LVDS Output Switching Characteristics. Upon asserting the power down function (PWDN = Low), and if the Pre-emphasis feature is enable, it is possible for the driver output to source current for a short amount of time lifting the output common mode to VDD. To prevent this occurrence, a load discharge pull down path can be used on either output (1 kΩ to ground recommended). Alternately, a commonly deployed external failsafe network will also provide this path (see INPUT FAILSAFE BIASING). The occurrence of this is application dependant, and parameters that will effect if this is of concern include: AC coupling, use of the powerdown feature, presence of the discharge path, presence of the failsafe biasing, the usage of the pre-emphasis feature, and input characteristics of the downstream LVDS Receiver. PRE-EMPHASIS Pre-emphasis dramatically reduces ISI jitter from long or lossy transmission media. One pin is used to select the pre-emphasis level for all outputs, off or on. The pre-emphasis boost is approximately 6 dB at 750 MHz. Table 1. Pre-emphasis Control Selection Table PEM Pre-Emphasis 0 Off 1 On INPUT FAILSAFE BIASING Failsafe biasing of the LVDS link should be considered if the downstream Receiver is ON and enabled when the source is in TRI-STATE, powered off, or removed. This will set a valid known input state to the active receiver. This is accomplished by using a pull up resistor to VDD on the ‘plus’ line, and a pull down resistor to GND on the ‘minus’ line. Resistor values are in the 750 Ohm to several kΩ range. The exact value depends upon the desired common mode bias point, termination resistor(s) and desired input differential voltage setting. Please refer to application note AN-1194 “Failsafe Biasing of LVDS interfaces” (SNLA051) for more information and a general discussion. DECOUPLING Each power or ground lead of the DS15BR400 should be connected to the PCB through a low inductance path. For best results, one or more vias are used to connect a power or ground pin to the nearby plane. Ideally, via placement is immediately adjacent to the pin to avoid adding trace inductance. Placing power plane closer to the top of the board reduces effective via length and its associated inductance. 8 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: DS15BR400 DS15BR401 DS15BR400, DS15BR401 www.ti.com SNLS224G – AUGUST 2006 – REVISED APRIL 2013 Bypass capacitors should be placed close to VDD pins. Small physical size capacitors, such as 0402, X7R, surface mount capacitors should be used to minimize body inductance of capacitors. Each bypass capacitor is connected to the power and ground plane through vias tangent to the pads of the capacitor. An X7R surface mount capacitor of size 0402 has about 0.5 nH of body inductance. At frequencies above 30 MHz or so, X7R capacitors behave as low impedance inductors. To extend the operating frequency range to a few hundred MHz, an array of different capacitor values like 100 pF, 1 nF, 0.03 µF, and 0.1 µF are commonly used in parallel. The most effective bypass capacitor can be built using sandwiched layers of power and ground at a separation of 2–3 mils. With a 2 mil FR4 dielectric, there is approximately 500 pF per square inch of PCB. The center dap of the WQFN package housing the DS15BR400 should be connected to a ground plane through an array of vias. The via array reduces the effective inductance to ground and enhances the thermal performance of the WQFN package. INPUT INTERFACING The DS15BR400 and DS15BR401 accept differential signals and allow simple AC or DC coupling. With a wide common mode range, the DS15BR400 and DS15BR401 can be DC-coupled with all common differential drivers (i.e. LVPECL, LVDS, CML). The following three figures illustrate typical DC-coupled interface to common differential drivers. Note that the DS15BR400 inputs are internally terminated with a 100Ω resistor while the DS15BR401 inputs are not, therefore the latter requires external input termination.

Figure 14 illustrates typical DC-coupled interface to common differential receivers and assumes that the receivers have high impedance inputs.
