Epson Electronics America introduced series of voltage controlled crystal oscillators (VCXO) designed for optical networking and LTE base stations.
The Epson VG-4513CB uses a high-frequency fundamental crystal to achieve output frequencies up to 500 MHz with no spurs and very low phase noise and low jitter.
The company said its new device is 87% smaller than existing VCXOs. It can deliver output frequencies up to 500 MHz without using a PLL or frequency multiplier.

You just read about All. A technology from the archive that helped get us here:
Google/Alphabet Project Loon served 2011–2021. What ultimately replaced it?
Google/Alphabet Project Loon solar-powered balloons drifting in the stratosphere (~20 km), steering by rising and falling into different wind layers, relaying LTE from ground stations to phones far below. Its job passed to Unit economics — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
