Renesas Electronics Corporation Clock Generators, PLLs, Frequency Synthesizers 5P49V5901B651NLGI8

The 5P49V5901B651NLGI8 is a programmable clock generator designed for high-performance applications in consumer electronics, networking, industrial, computing, and data communications. It supports up to four independent output frequencies generated from a single reference clock, with input frequency ranges accommodating LVCMOS, LVDS, LVPECL, and HCSL signals from 1 MHz to 350 MHz. The device features a low phase noise PLL with typical phase jitter of less than 0.7 ps, making it compliant with PCIe Gen1, 2, 3, and USB 3.0 standards. Configurations can be stored in on-chip One-Time Programmable (OTP) memory or modified via an I2C interface, allowing for flexibility in system design. The clock generator includes redundant clock inputs with a glitchless manual switchover function, and it can be configured for different operating modes and regional standards. Each output pair can be independently set to various voltage levels (1.8V, 2.5V, 3.3V) and supports programmable features such as loop bandwidth, output skew, slew rate control, and individual output enable/disable. The device is housed in a compact 24-pin VFQFPN package and operates within an industrial temperature range of -40¬8C to +85¬8C, making it suitable for a wide range of applications including Ethernet switches, PCI Express devices, and telecom line cards.
