CXT6176 Performance Specifications
CXT8192 Performance Specifications
CXT8192A Performance Specifications (Notes 4, 5)
Notes: 1. With Cload varying from 11.6 to 37.0 pF at a given temperature.
2. Measured at -40 to 85
°C.
3. Measured with Saunders 150D meter at 25
°C.
4. The CXT8192A crystal is designed to meet CTR12 jitter attenuation requirements for E1 applications
when used with the CS61575, CS61304A, and CS61305A line interface devices.
5. Due to tighter total frequency range tolerances, the CXT8192A must be placed within 0.5 inches of
device crystal pins and cut-outs should be made in power and ground planes beneath the crystal traces
to minimize parasitic capacitance.
