    In order to achieve exact bitrate control for use in SFN networks, the ASI-IP-GTW may be equipped with 1PPS/10MHz interface modules. The purpose is to lock the internal system clock of the ASI-IP-GTW to external 1PPS/10MHz signals to obtain exact bitrate control. The typical application is to receive a stream over IP network and send it out on ASI connectors at a fixed, accurate rate.

    The parameters are as follows: Regulator state: Shows “Idle”, “Waiting” or “Fine tune” dependent on the selected mode. In the “Waiting” state, the ASI-IP-GTW waits for a valid input signal to lock to. After some seconds with valid input signal, the regulator enters the “Fine tune”...
