Renesas’ Timing product portfolio has been acquired by SiTime.
Datasheets, documentation, and sample orders remain available on Renesas.com through late 2026. For new designs, purchasing, support, and product inquiries, visit SiTime.com or send an email to [email protected]. Full transition to SiTime is expected by late 2026.

The 81006 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 81006 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.
