CF5074A VCXO Module IC with Built-in Varicap .. OVERVIEW The CF5074A is VCXO module IC with built-in varicap diodes. The integrated varicap diode Bi CMOS process allows the device to be fabricated on a single chip. A newly developed oscillator circuit Features reduced drive level of crystal and wide pullrange. A VCXO module can be constructed with just the connection of a crystal unit, making the devices ideal as surface-mounted, pact VCXO modules. Features I I I I I I 2.25 to 3.6V operating supply voltage range 50MHz to 80MHz operating frequency range Varicap diode built-in Oscillation start-up detector function CMOS output duty level 4m A (min) output drive capability 15p F output load Standby function - High impedance in standby mode Bi CMOS process Chip form (CF5074A) APPLICATIONS VCXO modules ORDERING INFORMATION Device CF5074A- 1 CF5074A- 3 Package Chip form SEIKO NPC CORPORATION - 1 PAD LAYOUT (Unit: µm) ..
