NOTES:
ANALOG TRANSMISSION PERFORMANCE
(V DD = 2.7 to 3.6 V, V SS = 0 V, All Analog Signals Referenced to V AG , 0 dBm0 = 0.436 Vrms = – 5 dBm @ 600 , FST = FSR = 8 kHz,
BCLKT = MCLK = 2.048 MHz Synchronous Operation, T A = – 40 to + 85 C, Unless Otherwise Noted)
Peak Single Frequency Tone Amplitude without Clipping
Absolute Gain (0 dBm0 @ 1.02 kHz, T A = 25 C, V DD = 3.0 V)
Absolute Gain Variation with Temperature @ 3.0 V
Absolute Gain Variation with Power Supply (T A = 25 C)
Gain vs Level Tone (Mu–Law, Relative to – 10 dBm0, 1.02 kHz)
Gain vs Level Pseudo Noise, CCITT G.712
Total Distortion, 1.02 kHz Tone (Mu–Law, C–Message Weighting)
Total Distortion, Pseudo Noise, CCITT G.714 (A–Law)
Idle Channel Noise (For A/D, See Note 1)
Frequency Response (Relative to 1.02 kHz @ 0 dBm0)
In–Band Spurious (1.02 kHz @ 0 dBm0, Transmit and Receive)
Out–of–Band Spurious at V AG Ref (300 to 3400 Hz @ 0 dBm0 in)
Idle Channel Noise Selective (8 kHz, Input = V AG , 30 Hz Bandwidth)
Absolute Delay (1600 Hz)
Group Delay Referenced to 1600 Hz
Crosstalk of 1020 Hz @ 0 dBm0 from A/D or D/A (Note 2)
Intermodulation Distortion of Two Frequencies of Amplitudes
(A–Law, Relative to – 10 dBm0)
(– 4 to – 21 dBm0 from the Range 300 to 3400 Hz)
1. Extrapolated from a 1020 Hz @ – 50 dBm0 distortion measurement to correct for encoder enhancement.
2. Selectively measured while stimulated with 2667 Hz @ – 50 dBm0.
