Description
One-chip tunable voltage controlled crystal oscillator (VCXO) allows precise system frequency tuning 3.3V operation 8 pin SOIC and MSOP packages Uses inexpensive 20pF pullable crystals with no external capacitors required. 12mA drive capability at TTL levels
The T73227 is a single-chip, low-jitter Voltage-ControlledCrystal-Oscillator. The device accepts a 27 MHz, 20 pF crystal, and produces a low jitter output at the same frequency. A 0 to 3.0V control signal is used to fine tune the output clock frequency in the ±100ppm range. This finds use in systems that have frequency matching requirements, such as digital satellite receivers.
