OL2300 - NXP

OL2300 Fractional-N PLL based transmitter

The OL2300 is a UHF ASK/FSK fractional-N transmitter with a fully integrated fractional-N Phase-Locked Loop (PLL) frequency synthesizer and a power amplifier to drive an external antenna. The OL2300 is especially designed for use in the Industrial Scientific Medical (ISM) frequency bands (315/434/868/915 MHz). Fine-tuning of the reference oscillator by means.
