GPS Timing Module

The CW25-TIM is a small OEM surface mount GPS module that has been specifically designed for use in synchronization and timing applications.

The CW25-TIM has an on-board programmable NCO oscillator that outputs a synthesized frequency up to 30 MHz that is steered by the GPS receiver.

The CW25-TIM has a self survey mode of operation that allows the receiver to enter a position hold mode to allow accurate timing to be continued with only one satellite being tracked. The output frequency is highly accurate and can achieve full PRC MTIE performance; and can also track satellites and provide GPS synchronization in weak signal areas such as indoor applications. This reduces the need for high antenna placement typically in many environments.

The CW25-TIM is an exceptionally small surface mount package (25mm x 27mm x 4mm) with a highly integrated architecture that requires the minimum of external components allowing easy integration into host systems
