The functional block diagram is shown in figure 1. The SY05-HLPL receives two reference signals, usually 19.44MHz and using PLL synthesizer generates a high frequency signal necessary for transceivers or framers. The PLL that is complemented by high-speed logic that provide processing, switching between the timing modes, alarm and status messages and etc. A high quality VCXO provides very low jitter at the output. The additional output is provided using a divider. The module supports two operating modes: AUTO mode is the mode where all switching are done automatically and MANUAL mode is where unit will switch according to the two external control pins CON1 and CON2. CON1 0 1 0 1 CON2 0 0 1 1 Operational mode Free-run (Unlocked) Locked to EX REF 1 Locked to EX REF 2 Locked to TLB REF The module operates in the following four timing modes: 1) Free-run, 2) Locked to EX REF1, 3) Locked to EX REF2 and 4) Locked to TBL REF. Free-run it a mode the unit is unlocked to either of the inputs. The accuracy of the output frequencies in this mode is equal to the accuracy of free running VCXO. Locked to EX REF 1 is the mode where the output of the module is phase locked to input reference 1. Locked to EX REF 2 is the mode where the output of the module is phase locked to input reference 2, Locked to TBL REF is the mode where is the output of the module is phase locked to the signal used in Time Loop-back operation. th RALTRON ELECTRONICS CORP. ! 10651 N.W.19 St !
