GENERAL DESCRIPTION
The MSM7617 cancels echoes (acoustic or line echoes) generated in voice
channels. It is a lowpower CMOS LSI device with two channels.
MSM7617 echo canceling is performed by digital signal processing. It negates
echoes by estimating the echo channel and then generating a pseudo-echo
signal.
FEATURES
• Echo canceler has two channels, which can be used for acoustic and line
echoes. Set as a single cross-connected channel, it can be used for both
acoustic and line echoes.
• ITU-T G164/G165 standard tone disabler.
• PCM line level adjustment possible with SIN level attenuator (SA pin) and
SOUT level amplifier (SG pin). Can also be used for ERL amplification with the
SIN level attenuator (SA pin).
• RGC pin provides input/output adjustment mode (±6LR mode) that can prevent
malfunction due to excessive inputs without changing the RIN-ROUT input/output
levels.
• Cancelable echo delay time: 55 ms (max.)
• Echo attenuation: 30 dB (typ.)
• Clock frequency: 18 to 20 MHz 19.2 MHz if using internal clock signal
• Power supply voltage: 4.5 to 5.5 V
• Package: 64-pin plastic QFP (QFP64-P-1414-0.80-BK)
• Product name: MSM7617-001GS-BK (m-law)
