Receiver With Terminated Failsafe ECL/PECL-to-LVTTL CONVERSION WITH TI's LVDS RECEIVER The various versions of emitter-coupled logic (i.e., ECL, PECL and LVPECL) are often the physical layer of choice for system designers. Designers know of the established technology and that it is capable of high-speed data transmission. In the past, system requirements often forced the selection of ECL. Now technologies like LVDS provide designers with another alternative. While the total exchange of ECL for LVDS may not be a design option, designers have been able to take advantage of LVDS by implementing a small resistor divider network at the input of the LVDS receiver. TI has taken the next step by introducing a wide common-mode LVDS receiver (no divider network required) which can be connected directly to an ECL driver with only the termination bias voltage required for ECL termination (VCC– 2 V). Figure 14 and Figure 15 show the use of an LV/PECL driver driving 5 meters of CAT-5 cable and being received by TI's wide common-mode receiver and the resulting eye pattern. The values for R3 are required in order to provide a resistor path to ground for the LV/PECL driver. With no resistor divider, R1 simply needs to match the characteristic load impedance of 50 Ω. The R2 resistor is a small value and is intended to minimize any possible common-mode current reflections.
