81006I - Block Diagram
説明
The 81006I is a high performance, low jitter/ low phase noise VCXO and is a member of the family of high performance clock solutions from IDT. The 81006I works in conjunction with a pullable crystal to generate an output clock over the range of 12MHz - 31.25MHz and has 6 LVCMOS outputs, effectively integrating a fanout buffer function.
The frequency of the VCXO is adjusted by the VC control voltage input. The output range is ±100ppm around the nominal crystal frequency. The VC control voltage range is 0 - VDD. The device is packaged in a small 4mm x 4mm VFQFN package and is ideal for use on space constrained boards typically encountered in ADSL/VDSL applications.
