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. - INPUT REFERENCE SELECTION CNT 0 1 Reference selected REF A REF B - OUTPUT PROGRAMMING EN OUT 0 1 0 FREE-RUN 0 X 1 FRS output 0 0 1 OUTPUT Locked to Reference Hi-Z Tri-State Free-Run - ALARM STATES LOL 0 1 0 LOR 0 0 1 ALARM 0 -No alarm 1- Loss of Lock 1-Loss of Reference th RALTRON ELECTRONICS CORP. ! 10651 N.W.19 St !
