- DESCRIPTION
The SY02-HP2O is a High Frequency Phase Lock Loop has been designed as a module level subsystem for easy incorporation into telemunication equipment. The module generates the high frequency (up to 622.08MHz) output from a low jitter VCXO or VCSO (SAW based oscillators). The output can be disabled externally by setting OUTEN pin high. The SY02-HP2O can be locked to one reference of a pre-selected input frequency between 8 k Hz to 77.76MHz. The module has fast locking time and tolerates reference inputs with different duty cycles. The loop bandwidth is optimized according to used VCXO and wanted output performance. The SMD package dimensions are 0.75x1.20 inch and power supply is 3.3V. Parts are assembled using high temperature solder to withstand surface...
