Features
Synchronizes to clock-and-sync-pair to maintain
minimal phase skew between inputs and outputs
Supports output wander and jitter generation
specifications for SONET/SDH and PDH
interfaces
Accepts three input references and synchronizes
to any combination of 2 kHz, 8 kHz, 1.544 MHz,
2.048 MHz, 8.192 MHz, 16.384 MHz or 19.44 MHz
inputs
Provides a range of clock outputs:
-
2.048 MHz (E1), 16.384 MHz and either
4.096 MHz and 8.192 MHz or 32.768 MHz and
65.536 MHz
-
19.44 MHz (SONET/SDH)
-
1.544 MHz (DS1) and 3.088 MHz
-
a choice of 6.312 MHz (DS2), 8.448 MHz (E2),
44.736 MHz (DS3) or 34.368 MHz (E3)
Provides 5 styles of 8 kHz framing pulses and a
2 kHz multi-frame pulse
Provides automatic entry into Holdover and return
from Holdover
Manual and automatic hitless reference switching
Provides lock, holdover and accurate reference
fail indication
Selectable loop filter bandwidth of 29 Hz or
922 Hz
Less than 24 ps
rms
intrinsic jitter on the
19.44 MHz output clock, compliant with GR-253-
CORE OC-3 and G.813 STM-1 specifications
Less than 0.6 ns
pp
intrinsic jitter on all PDH output
clocks and frame pulses
Selectable external master clock source: clock
oscillator or crystal
Simple hardware control interface
