Time Code (IRIG A/B/G
IEEE1344, IEEEC37.118, AFNOR NF S87-500) receiver slot card, with the following
features:
- TCXO oscillator
- Single lane (x1) PCI Express (PCIe) Interface, PCI Express r1.0a compatible
(Gen1, 2.5 Gbps).
1 x modulated Time Code (IRIG A/B/G, IEEE1344, IEEEC37.118, AFNOR NF S87-500)
input.
Input impedance settable (50, 600 (default),
5000 Ohm), via isolated, female BNC connector.
1 x unmodulated (DC level shift) Time Code (IRIG A/B, IEEE1344, IEEEC37.118,
AFNOR NF S87-500) input.
Isolated by photocoupler, via 9 pin D-SUB male
connector of the Multiref port.
-> IRIG G also available
(requires modification).
1 x RS232 interface COM0, via 9 pin D-SUB male connector.
3 x pulse outputs (TTL). Free programmable with pulses, switching times,
frequency synthesizer or Time Code.
Preset to:
PPO0: pulse per second (PPS), active high,
pulse duration 200 msec.
PPO1: pulse per minute (PPM), active high,
pulse duration 200 msec.
PPO2: DCF77 compatible pulses (TTL),
active high.
2 x time capture input (TTL).
1 x 10 MHz standard frequency (TTL).
Multiref Port (optional)
To use the Multiref port inputs/outputs, this should be connected to a 9-pin
D-SUB connector.
For this, the available D-SUB connector can be used. If the standard port and
the Multiref port is needed, a D-SUB on an extension slot, is required.
1 x PPS Input (TTL).
1 x RS232 interface COM1, via 9pin D-SUB male connector.
2 x pulse outputs (TTL). Free programmable with pulses, switching times,
frequency synthesizer or Time Code.
Preset to:
PPO0: pulse per second (PPS), active high,
pulse duration 200 msec.
PPO1: pulse per minute (PPM), active high,
pulse duration 200 msec.
1 x 10 MHz standard frequency (TTL).
1 x unmodulated (DC level shift) Time Code (IRIG A/B, IEEE1344, IEEEC37.118, AFNOR
NF S87-500) input. Isolated by photocoupler.

(requires modification)
4 x status LEDs.
- memory mapped I/O time reads.
- Low profile board (69 x 150 mm).
