Product Description
The module TCR180 has been designed to receive and to generate IRIG-A/B, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 time codes.
It is used in applications like data acquisition, standalone computer time synchronization (for systems without a network connection or higher accuracy requirements) or as an IRIG converter device.
Receiver:
The module provides two input channels for decoding of modulated and unmodulated time codes in IRIG-A/B, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 format. The receiver's automatic gain control (AGC) allows the reception of modulated IRIG signals within an amplitude range from 600 mVpp to 8 Vpp. In addition, the TCR180 provides an optocoupler input for decoding unmodulated codes with TTL- or RS-422 level for example.
Generator:
The board TCR180 can generate time codes in IRIG-A/B, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 format. These signals are provided as modulated (3 Vpp/1 Vpp into 50 ohm) and unmodulated (TTL into 50 ohm) time codes.The independent configuration of the time code and its offset to UTC of the receiver and the generator allows the use of TCR180 for time code conversion applications.
