The 5410 series are VCXO module ICs supported 20 MHz to 62 MHz fundamental oscillation. They employ a recently developed varicap diode fabrication process at fixation Communication usage that provides a low phase noise characteristic and a wide frequency pulling range without any external components. The 5410 series are ideal for wide pulling range, low phase noise, VCXO modules. Operating temperature range is -40°C to 105°C
