DESCRIPTION
The SY02-PLL 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. The SY02-PLL can lock to one of four reference frequencies from 8 to 64kHz that can be selected using to external select pins. The counters, phase detector and other logic are implemented in programmable logic. The loop bandwidth is optimized according to used VCXO and wanted output performance. The two output signals monitor the status of the phase loop LOL (Loss of Lock) and LOR (Loss of Reference). 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. - INPUT REFERENCE SELECTION
