TCR511PCI:
IRIG Time Code Receiver for Computers - PCI/PCI-X bus

The TCR511PCI receivesIRIG-A/B or AFNOR time codes and uses them to synchronize the system time of the host PC

The board TCR511PCI was developed for computer systems with PCI-bus. It is designed as an universal board and can be used in systems with either 3.3 V or 5 V PCI slots therefore. The module supports clock speeds of 33 MHz and 66 MHz.

TCR511PCI serves to receive and decode modulated (AM) and unmodulated (DC Level Shift) IRIG and AFNOR time codes. AM-codes are transmitted by modulating the amplitude of a sine wave carrier, unmodulated codes by variation of the width of pulses.

Automatic gain control within the receive circuit for unmodulated codes allows decoding of IRIG signals with a carrier amplitude of 600 mVpp to 8 Vpp. The input stage is elecctically insulated and has an impedance of 50 Ω, it is accessible via the BNCconnector in the bracket of TCR511PCI.

Unmodulated time codes must be connected to the D-Sub-plug of the module. An onboard photocoupler insulates the internal receive circuit. In delivery state of TCR511PCI the contacts of the D-Sub-plug are not connected to the photocoupler. Two DIP-switches must be set to the ‘ON’ position for making this connection.
