TLSI crystal oscillators exhibit low-jitter

TLSI Inc. has introduced the T73227 and T83027 high-precision Voltage Controlled Crystal Oscillator (VCXO) clock generator ICs that are designed to exhibit low-jitter and low phase noise performance.

The T73227 is designed to accept an input from a standard 27MHz quartz crystal and allows the output frequency to be adjusted or "pulled" by a variable control voltage input. The product's pin compatible companion, the T83027, accepts an input from a standard 13.5MHz crystal and utilizes a phase-locked loop (PLL) design to produce the required 27MHz output frequency clock. The T83027 offers a pin-for-pin compatible alternative to the MK3727.

Typical tuning frequency range is ±150ppm (T73227) and ±100ppm (T83027), and both devices operate from the nominal 3.3V power supply.

The T73227 is available in 8-pin SOIC and MSOP and is priced at 60 cents, while the T83027 is offered in 8-pin SOIC package and is priced at less than $1. Both prices are for 10,0000-piece quantities.
