28 / 33 page  AMPLITUDE RESPONSE Receive path Symbol Parameter Test Condition Min. Typ. Max. Unit GRAE Receive Gain Absolute Accuracy Receive gain programmed for maximum Apply 0 dBm0 PCM code to DR Measure VFr+ -0.3 0.3 dB GRAL Receive Gain Absolute Accuracy Receive gain programmed for maximum Apply 0 dBm0 PCM code to DR Measure LS+ -0.6 0.6 dB GRAGE Receive Gain Variation with programmed gain Measure Earpiece Gain over the range from Maximum to minimum setting. Calculate the deviation from the programmed gain relative to GRAE, i.e. GRAGE =G actual -G prog. -GRAE -0.5 0.5 dB GRAGL Receive Gain Variation with programmed gain Measure Loudspeaker Gain over the range from Maximum to minimum setting. Calculate the deviation from the programmed gain relative to GRAL, i.e. GRAGL =G actual -G prog. -GRAL -1.0 1.0 dB GRAT Receive Gain Variation with temperature Measured relative to GRA. (LS and VFr) GR = Maximum Gain -0.1 0.1 dB GRAV Receive Gain Variation with Supply Measured relative to GRA. (LS and VFr) GR = Maximum Gain -0.1 0.1 dB GRAF Receive Gain Variation with frequency (Earpiece or Loudspeaker) Relative to 1015,625 Hz, multitone test technique used. min. gain < GR < Max. gain f = 200 Hz f = 300 Hz to 3000 Hz f = 3400 Hz f = 4000 Hz -0.3 -0.3 -0.8 0.3 0.3 0.0 -14 dB dB dB dB GRAL E Receive Gain Variation with signal level (Earpiece) Sinusoidal Test Method Reference Level = –10 dBm0 DR = 0 dBm0 to +3 dBm0 DR = -40 dBm0 to 0 dBm0 DR = -50 dBm0 to -40 dBm0 DR = -55 dBm0 to -50 dBm0 -0.25 -0.25 -0.5 -1.5 0.25 0.25 0.5 1.5 dB dB dB dB GRAL L Receive Gain Variation with signal level (Loudspeaker) Sinusoidal Test Method Reference Level = –10 dBm0 DR = 0 dBm0 to +3 dBm0 DR = -40 dBm0 to 0 dBm0 DR = -50 dBm0 to -40 dBm0 DR = -55 dBm0 to -50 dBm0 -0.25 -0.25 -0,5 -1.5 0.25 0.25 0.5 1.5 dB dB dB dB ST5088 28/33 |
