The TCR180PEX-EL receives IRIG-A/B, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 time codes and can be used for synchronizing the system time of its host PC.

It is used in applications like data acquisition, standalone computer time synchronization (for systems without a network connection or higher accuracy requirements).

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 format. The receiver's automatic gain control (AGC) allows the reception of modulated timecode signals within an amplitude range from 600 mVpp to 8 Vpp. In addition, the TCR180PEX-EL provides an optocoupler input for decoding unmodulated codes with TTL- or RS-422 level for example. The board can be delivered with an optical input for unmodulated codes optionally.

The decoded date and time can be read via the PCI Express interface and is also transmitted via the board's RS-232 port. A buffered real time clock keeps time and date after power down.
