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

NOTES ON USE
1. Only one of the FSK generation function, tone generation function (DTMF generation function) and dial pulse
2. Using the 2100 Hz single tone/phase inversion detection function and the tone detection function for each
3. If the melody generation function is used, stop all the functions described below on the DSP side that generates
• Tone generation function (TGEN0/TGEN1)
• Tone detection function (TONE_RXDET0/TONE_TXDET0, TONE_RXDET1/TONE_TXDET1)
• FSK generation function (FSKGEN0/FSKGEN1)
• Tone disabler detection function (TD_RXDET0/TD_TXDET0, TD_RXDET1/TD_TXDET1)
• DTMF detection function (DTMF_DET0/DTMF_DET1)
• Echo cancellers (EC0/EC1)
• Dial pulse detection function (DPDET0/DPDET1)
• Dial pulse transmission function (DPGEN0/DPGEN1)
• Timer (TIMER)
