The VersaClock 3S programmable clock generators are designed for low power, consumer, and high performance PCI Express applications. The 5P35023 generates up to 5 output frequencies (3 Single-Ended and 2 Differential) out of a crystal or clock input. The 5P35021 generates up to 3 frequencies (1 Single-Ended and 2 Differential). The 5L35023 and 5L35021 devices are lower-power 1.8V versions of the 5Pxxxxx devices. Use the form below to configure your custom device.
