The LC-XO-PLUS GPSDO 10 MHz reference kit is a complete solution for providing extremely accurate 10 MHz, 1 PPS, and Position-Velocity-Time information anywhere in the world. It includes a high-performance GPS receiver that can acquire and route up to 50 GPS signals to a state of the art –160 dBm, low-noise 5 V CMOS, 10 MHz and 3.3 V CMOS 1 PPS output, USB control interface, precision voltage references, and DACs. It generates a low-noise 10 MHz signal with typically better than 1E-10 precision and accuracy (0.1ppb), better than 250 fs jitter (20 Hz to 2 MHz), and a 1 PPS signal with typically better than +/-25 ns stability when locked to GPS.

The unit is built as an easy-to-use small, enclosed box that operates and receives power by plugging into a PC USB port and into the supplied GPS antenna. The unit also provides a TTL level status output and is operational from an optional 5V power supply. The board is supplied with a USB cable, power supply, two MMCX to BNC adaptor cables, a GPS antenna with 10 m length, Z38xx control, plotting, a Windows-based command application, and a quick-start guide.
