Renesas Electronics Corporation Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers IDT5V9885CPFI8

The IDT5V9885CPFI8 is a 3.3V EEPROM programmable clock generator designed for high-performance applications in data communications, telecommunications, consumer electronics, and networking. It features three internal phase-locked loops (PLLs), each capable of generating unique non-integer-related frequencies from a single reference clock, with input frequency ranges from 1MHz to 400MHz and output frequency ranges from 4.9kHz to 500MHz. The device supports a reference crystal input with a frequency range of 8MHz to 50MHz and includes programmable oscillator gain and linear load capacitance. Each PLL is equipped with an 8-bit pre-scaler and a 12-bit feedback divider, allowing for precise frequency generation. The clock generator also offers programmable loop bandwidth settings, enabling users to optimize jitter performance. Additional features include support for spread spectrum generation on two PLLs, multiple I/O standards (3.3V LVTTL/LVCMOS, LVPECL, and LVDS), programmable slew rate control, and glitchless clock input switchover. The IDT5V9885CPFI8 can be programmed via JTAG or I2C interfaces, and its internal EEPROM allows for configuration storage, facilitating in-system programmability. The device is available in both TQFP and VFQFPN packages and operates within an industrial temperature range of -40 to +85°C.
