GPS-LC-8

Product catalog summary

Overview
The GPS-LC-8 is a cost-effective time-frequency reference generator designed by Digital Instruments S.r.l. It offers high-performance signal synchronization with unbeatable market pricing. The device features 8 independent outputs for both 10 MHz frequency and PPS (Pulse Per Second) time references, ensuring high stability through GPS-controlled tuning algorithms. It is suitable for applications requiring simultaneous time-frequency references for multiple devices, providing complete electrical isolation and monitoring for anomalies.

Features
The GPS-LC-8 includes a high-stability OCXO oscillator with minimal frequency drift, a 12-channel GPS receiver with error management, and a fast-lock DPLL design. It provides 8 sine wave outputs at 10 MHz with 13 dBm power and 8 PPS outputs with TTL level. The device supports NTP synchronization via Ethernet and features dual power supply options. It is housed in a 19'' 1U rack-mountable design.
