1204A DIGITAL SIGNAL DISTRIBUTION

The ptf 1204A Digital Signal Distribution unit is a flexible platform used for distribution of various pulse formats (ex. 1 PPS, 1 PPM, 10 PPM, etc). The ptf 1204A will also distribute digital timing signals such as IRIG-B DCLS format. In order to cater for a wide range of input pulse frequencies, the ptf 1204A design utilizes a CPLD with jumper selectable alarm delays to
correct alarm on the various pulse frequencies. The unit reproduces precision pulse input signals with the minimum of propagation delays.

The unit uses high speed signal buffering to distribute the input signal to 12 separate outputs and maintain the quality of the input signals
