Functional Description

CY2037 is an EPROM-programmable, high accuracy, PLL-based die designed for the crystal oscillator market. The die attaches directly to a low cost 10 to 30 MHz crystal and can be packaged into a 4-pin through-hole or surface mount packages. The oscillator devices may be stocked as blank parts and custom frequencies programmed in-package at the last stage before shipping. This enables fast-turn manufacture of custom and standard crystal oscillators without the need for dedicated, expensive crystals.
