LC-XO GPS Disciplined Oscillator
At only 0.97 x 0.97 inches in size, the LC-XO is the smallest true GPS-Disciplined-Oscillator (GPSDO) on the market today. The LC-XO was designed to be soldered onto a customer PCB or plugged into a standard 100-mil pin-spacing DIP socket for optional retrofitting. The LC-XO is designed for high-volume, low-cost production applications. It provides all the software features of the larger GPSDO such as full SCPI command support, NMEA output support, a WAAS/EGNOS/MSAS 50-channel GPS receiver, a 10 MHz and 1 PPS input, a 1 PPS output, and field- upgradable firmware.
The LC-XO is available in either OCXO or TCXO versions and represents the smallest SWAP GPSDO on the market today. Phase noise and frequency stability are not compromised, and the unit achieves a -155 dBc/Hz noise floor with better than 5 parts per trillion frequency stability over 5 hours of operation. The unit includes internal 3.3 V to 5 V DC-DC power supplies and filters and can provide 5 V at up to 50 mA to external customer circuitry, as well as to the external GPS antenna. The unit provides ALARM/EVENT/LOCK status signals in TTL format and serial format and has a dual LED on board for status indication.
