VC America's high stability clocks offer improved temperature stabilities versus standard CMOS clock oscillators and operate over -55°C to 125°C range with better stabilities ±10ppm to ±25ppm, and -55°C to 85°C to ±10ppm.

Some high temperature clock and RTC products are capable of operation to 200°C.


VC America started in 2002 supplying Seiko NPC semiconductor products and added LCC packaging, design and supply of HFF crystal technology, all to support hybrid clock manufacturers. We started manufacturing of subassemblies in 2004. In 2008, we added test for characterization and qualification of oscillators for extended temperature ranges as wide as -60°C to 150ׄ°C.

We expanded into optical Encoder [read heads and interpolation] and sensor products [Optical, Infrared, UV, Magnetic]. VC America developed precision rotary and linear scales and make custom scales to customer requirements.

VC America's introduced new high stability CMOS clocks with excellent temperature stabilities for military -55°C to 125°C operation with frequency stabilities ±10ppm to ±25ppm.
