California Micro Devices (CAMD), a leading manufacturer of thin film integrated passive devices (IPDs) and complementary semiconductor solutions, has introduced a nonlinear terminator integrated circuit specifically designed to minimise noise and reflections in high frequency digital electronics systems. The PACNLT101 minimises the reflections on high-speed data lines that lead to voltage overshoot disturbances, resulting in noise and possible data loss or improper system operation.
The manufacturer says that the PACNLT101 employs a fundamentally different technology as compared to the traditional methods of using resistors or Schottky diodes for data bus termination. This device overcomes many of the shortfalls that the current solutions are faced with. For example, resistive terminations are normally used to match the characteristic impedance of the transmission line on the PCB. These methods require impedance control on the PCB, increase power consumption and degrade output levels, resulting in reduced noise immunity. Traditional Schottky diodes are ineffective when the supply voltages drop below 3,3 V says CAMD.
The PACNLT101 can provide effective termination performance under variable loading and supply conditions. The device supports up to 16 terminated lines per package. A typical application may use four devices to replace (and outperform) 64 conventional Schottky diode pairs; improving the termination characteristics, providing significant reductions in component and assembly costs, improving manufacturing efficiency and reliability, and saving board area for space-critical designs. The PACNLT101 could find particularly effective use on memory buses where the loading of the transmission lines varies as a function of the number of memory modules inserted. According to the company the non-linear characteristics of the device make it somewhat self compensating in applications such as these.
