The IDT5V925BI is a high-performance, low skew, low jitter phase-locked loop (PLL) clock driver. It provides precise phase and frequency alignment of its clock outputs to an externally applied clock input or internal crystal oscillator. The IDT5V925BI has been specially designed to interface with Gigabit Ethernet and Fast Ethernet applications by providing a 125MHz clock from 25MHz input. It can also be programmed to provide output frequencies ranging from 3.125MHz to 160MHz with input frequencies ranging from 3.125MHz to 80MHz. The IDT5V925BI includes an internal RC filter that provides excellent jitter characteristics and eliminates the need for external components. When using the optional crystal input, the chip accepts a 10-30MHz fundamental mode crystal with a maximum equivalent series resistance of 50?. The on-chip crystal oscillator includes the feedback resistor and crystal capacitors (nominal load capacitance is 18pF).
