NOTE 7: The test condition is a 1-kHz input signal with a 16-kHz conversion rate. The load impedance for the DAC is 600 Ω. Input and output voltages are referred to Vref. 3.3.8 Transmit Channel Signal-to-Distortion Ratio (see Note 7) PARAMETER TEST CONDITIONS MIN MAX UNIT VI = – 6 dB to – 0.1 dB 58 VI = – 12 dB to – 6 dB 58 VI = – 18 dB to – 12 dB 56 VI = – 24 dB to – 18 dB 50 D/A channel signal-to-distortion ratio VI = – 30 dB to – 24 dB 44 dB VI = – 36 dB to – 30 dB 38 VI = – 42 dB to – 36 dB 32 VI = – 48 dB to – 42 dB 26 VI = – 54 dB to – 48 dB 20 NOTE 7: The test condition is a 1-kHz input signal with a 16-kHz conversion rate. The load impedance for the DAC is 600 Ω. Input and output voltages are referred to Vref. 3.3.9 Receive and Transmit Gain and Dynamic Range (see Note 8) PARAMETER TEST CONDITIONS MIN TYP† MAX UNIT Transmit gain tracking error C, I VO = – 48 dB to 0 dB signal range ±0.05 ±0.15 dB Receive gain tracking error C, I VI = – 48 dB to 0 dB signal range ±0.05 ±0.15 dB Transmit gain tracking error M VO = – 48 dB to 0 dB signal range, TA = 25°C ±0.05 ±0.25 dB Receive gain tracking error M VI = – 48 dB to 0 dB signal range, TA = 25°C ±0.05 ±0.25 dB Transmit gain tracking error M VO = – 48 dB to 0 dB signal range, ±0.4 dB Receive gain tracking error M O gg TA = – 55°C TO 125°C ±0.4 dB NOTE 8: Gain tracking is relative to the absolute gain at 1 kHz and 0 dB (0 dB relative to Vref). |
