Microsemi SyncServer S200, User Manual

Page: 93 / 190

IRIG-B Out
Wave Shape:Sine Wave or Square Wave
Impedance:> 50 k Ohms
Typical system oscillator pull-ranges:
n
TCXO 1E-6 (1 ppm)
n
OCXO 5E-7 (0.5 ppm)
n
Rubidium 1E-9 (1 ppb)
Note: If the 10MHz In signal is too noisy, the Hardware Clock may not be able to lock to it.
IRIG-B Out
Description:
IRIG Out
, provides a selected time code from the SyncServer's Hardware Clock. The
time code format is selected via the Web interface. Amplitude Modulated (AM) outputs are sup-
ported from the IRIG Out BNC. Also see
REFERENCES - IRIG-B (on page
51
).
Note: This feature is not available on the S200 model.
Connector:
IRIG Out
, BNC female
DCLS Amplitude: TTL into 50 ohms
AM Amplitude:3.5 ±0.5 Vpp into 50 Ohms
AM Ratio:3:1 ±10%
Selectable Time Code Output Formats:
n
IRIG-B
n
IRIG-B (Legacy TrueTime)
n
IRIG-B with IEEE 1344 extension
IRIG-B In
Description:
IRIG In
accepts a time code for input from an external timing reference into the Syn-
cServer's Hardware Clock. The time code format is selected via the Web interface. Supports
only amplitude modulated (AM) IRIG-B inputs. For the SyncServer to maintain lock to this sig-
nal, the stability of the time code input must be better than the pull-range of the system oscil-
lator. Also see
REFERENCES - IRIG-B (on page 51 )
Note: This feature is not available on the S200 model.
Connector: IRIG In , BNC female
DCLS Amplitude:<1.5 V for logic 0, >2.0 V for logic 1
AM Amplitude:1 to 8 Vpp
AM Ratio:2:1 to 4:1
Impedance:>5k Ohms
