DESCRIPTION
The SY02-PLL2 is a Phase Lock Loop has been designed as a module level subsystem for easy incorporation into
telecommunication equipment. The module generates the output from a low jitter VCXO and provides recovered
signal as secondary output. The SY02-PLL2 has two reference inputs with frequencies that can be selected by user
from 8 to 77.76MHz. The input reference selection pin (CNT) selects which reference will be used. The loop
bandwidth is optimized according to used VCXO and wanted output performance. The ALARM output signal
monitors the status of the phase loop in case of Loss of Lock (LOL) and Loss of Reference (LOR) both internal
signals. The two control inputs provides module to go into free-run regardless of the reference (FREE_RUN) and to
the tri-state high impedance output (OUT EN). The SMD package dimensions are 19.4 x 20.3 mm and power supply
is 3.3V.
