The board TCR170PEX is a standard height board for computers with PCI Express interface. The data transfer to the computer is done by using a single PCI Express Lane - x1 board. TCR170PEX serves to decode and generate modulated and unmodulated (AM and 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.

As standard the module TCR170PEX is equipped with a TCXO (Temperature Compensated Xtal Oscillator) as master oscillator to provide a high accuracy in holdover mode of +/- 1 * 10E-8. Optionally an OCXO (Oven Controlled Xtal Oscillator) is available for better accuracy.
