5.2 Temperature Stability

Crystal tend to have a high dependability on temperature, with the frequency varying significantly as temperature increases. Supporting a 25-ppm part at extended industrial grade (115°C LVCMOS/105°C differential), is not possible without adding some temperature compensation circuitry. LMK6C/D/P/H BAW oscillator meets ±10 ppm budget across full temperature range.
