Product Description

The board TCG510 has been designed for the generation of IRIG and AFNOR standard time codes. Particularly it is intended for operation with the Meinberg GPS receivers GPS161, GPS163 and GPS167 as well as the DCF77 correlation receiver PZF509. Apart from the digitally generated amplitude-modulated code, TCG510 also provides the unmodulated DC level shift code. The modulated sine wave carrier and the board's internal time pattern are derived from the radio clock's disciplined oscillator. For special applications, the board can be equipped with a freewheeling oscillator (OCXO or TCXO). Signals required for operation are a synchronous pulse per second signal (PPS), a serial time string at RS232 level, and a 10MHz reference clock as mentioned above.
