• Manufacturer Part Number: ml7084-001
• Description: 4ch Voip Codec
• Manufacturer: Oki Semiconductor

G. Internal data memory for MGEN gain control
H. Internal data memory for MGEN total gain control
(Note)
Set the above output level so that the amplitude value and level after each track synthesis do not exceed the
maximum amplitude of 1.3 Vp-p and the maximum level of 3.17 dBm0.
I. Internal data memory for MGEN fade control
(Note) To regenerate multiple tracks, it is necessary to make the time for each track identical.
OKI Semiconductor
Each output level of MGEN_TRACKm is –13.3 dBm0 at 0 dB with the initial value.
