0 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, s...
