All analog signals are referenced to VAG unless otherwise noted.
Power Supply Rejection Ratio is for Longjing IC only. Total PSRR from battery to output is obtained by summing the
PSRR from Neptune to the one from the Regulator in Seaweed. It is assumed that the regulators in Seaweed will
have a minimum PSRR of 45 dB.
For A/D differential input (ADC_P - ADC_M) 0dBm0 = 340mV
The codec output will not “foldback” or oscillate if overdriven, but clip.
The digital word corresponding to +3dBm0 is ‘0111111111111’b. Therefore if the audio level is set to +3dBm0, any
variation in gain could cause large distortion if the digital number exceeds ‘0111111111111’b. For this reason the
maximum recommended signal for low distortion is +3dBm0 − (Absolute Gain Error) = +2dBm0.
GSM Spec = –64 0dB.
This value is a preliminary target. The final number will be specified after obtaining the production statistical data.
Small frequency response deviation from straight line in the 60:200 Hz range is acceptable by spec requirements.
Small frequency response deviation from straight line in the 3400:4000 Hz range is acceptable by spec requirements.
Small frequency response deviation from straight line in the 3400:4000 Hz range is acceptable by spec requirements.
