AFNOR NFS 87-500
ACCURACY OF TIME BASE: +/-5
µ
sec compared to IRIG reference marker
REQUIRED ACCURACY OF
TIME CODE SOURCE:
+/- 100ppm
HOLDOVER MODE:
automatic switching to crystal time base
accuracy approximately 1E-6 if decoder has been
synchronous for more than 1h
BACKUP-BATTERY:
if the power supply fails, an onboard realtime
clock keeps time and date information, important
system parameters are stored in the RAM of the system
lifetime of the lithium battery at least 10 years

OPERATION:
microprocessor supervisory circuit provides watch
dog timer, power supply monitoring and backupbattery
switchover software watchdog monitors correct program
ow and generates a reset in case of error detection
INITIALIZATION:
software and realtime clock can be set by a serial
Meinberg Standard Telegram via COM0 or the
PCI-Express bus
