87972I-147 に関するリソース
説明
The 87972I-147 is a low skew, LVCMOS/LVTTL Clock Generator and a member of the family of High Performance Clock Solutions from IDT. The 87972I-147 has three selectable inputs and provides 14 LVCMOS/LVTTL outputs. The 87972I-147 is a highly flexible device. Using the crystal oscillator input, it can be used to generate clocks for a system. All of these clocks can be the same frequency or the device can be configured to generate up to three different frequencies among the three output banks. Using one of the single ended inputs, the 87972I-147 can be used as a zero delay buffer/multiplier/ divider in clock distribution applications. The three output banks and feedback output each have their own output dividers which allows the device to generate a multitude of different bank frequency ratios and output-to-input frequency ratios. In addition, 2 outputs in Bank C (QC2, QC3) can be selected to be inverting or non-inverting. The output frequency range is 10MHz to 150MHz. Input frequency range is 6MHz to 150MHz. The 87972I-147 also has a QSYNC output which can be used or system synchronization purposes. It monitors Bank A and Bank C outputs and goes low one period of the faster clock prior to coincident rising edges of Bank A and Bank C clocks. QSYNC then goes high again when the coincident rising edges of Bank A and Bank C occur. This feature is used primarily in applications where Bank A and Bank C are running at different frequencies, and is particularly useful when they are running at non-integer multiples of one another.
