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:
