Notes:
1. Dynamic characteristics are specified at 5.0V unless otherwise specified.
2. All logic inputs except Encoder and Decoder Data clocks
3. For and encoder/Decoder combination, Insertion loss contributed by a single component is half this figure.
4. Driven with a source impedance of <100Ω.
5. Recommended values – See Figures 4, 5, 6, and 7.
6. Group Delay Distortion for the full codec is relative to the delay with and 820Hz, -20dB signal at the
encoder input
7. An Emitter Follower output stage.
8. 4V = 80%VDD, 3.5V = 70%VDD, 1.5V = 30%VDD, 1V = 20%VDD
9. Analog Voltage Levels used: 0dBmO = 489mVRMS = -4dBm = 0dB. –15dBmO = 87mVRMS. –20dBmO =
49mVRMS = -24dBm.
