Notes to the characteristics
1. Crosstalk:
2. The transmission contains:
3. The oscillator is designed to operate together with MURATA resonator CSB503F58 or CSB503JF958 as SMD.
4. The internal SAP carrier level is determined by the composite input level and the level adjustment gain.
5. When reset is active the SMU-bit (SAP mute) and the LMU-bit (OUTL, OUTR mute) is set and the I
6. The AC characteristics are in accordance with the I
