OVERVIEW
The SM5023 series are 3rd overtone crystal oscillator module ICs. They feature built-in oscillator capacitors
with excellent frequency response. As cutoff frequency can be configured by using an external feedback resis-
tor R
cuit characteristics are optimized for a 3rd overtone oscillation by round blank. They also feature a built-in
output buffer with high output drive capability and are available in miniature 6-pin package, making them ideal
as DIP-type crystal oscillators.
