Clock Generators for Automotive Systems

Clock Generators for Automotive Systems

IDT’s VersaClock 6E 5P49V60 are high-performance programmable clock generators designed for automotive applications. These devices feature four banks of internal OTP memory, I2C interface, LVCMOS reference clock, redundant clock inputs, and four universal output pairs. The frequencies are generated from a single reference clock, which can come from one of the two redundant clock inputs. The selection of one of the redundant clocks during normal operation is made possible by the glitchless manual switchover function. They also have two select pins which allow up to four configurations to be programmed and are accessible using processor GPIOs or bootstrapping. These AEC-Q100-qualified clock generators can be configured to use one of the two I2C addresses to connect multiple devices that can be used in a system. Typical applications include automotive infotainment, dashboard systems, audio/video applications, camera, PCI Express 1.0/2.0/3.0, active antennas, and in-vehicle networking.
