VOICE-BAND AUDIO PROCESSOR (VBAP
)
SLWS103 – NOVEMBER 2000
2
POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
The human voice is effective from a frequency range of 300 Hz to 3300 Hz in telephony applications. In order
to eliminate unwanted signals, the VBAP design has two types of filters that operate in both the transmit and
receive path. A low-pass filter attenuates the signals over 4 kHz. A selectable high-pass filter cleans up the
signals under 100 Hz. This reduces noise that may have coupled in from 50/60-Hz power cables. The high-pass
filter is bypassed by selecting the corresponding register bit.
VBAP has many programming features that are controlled using a 2-wire standard serial I2C interface. This
allows the device to interface with many digital ICs such as a DSP or a microprocessor. The device has seven
registers: power control, mode control, transmit PGA, receive PGA, high DTMF, low DTMF, and auxiliary mode
control. Some of the programmable features that can be controlled by I2C interface include:
D Transmit amplifier gain
D Receive amplifier gain
D Sidetone gain
D Volume control
D Earphone control
D PLL power control
D Microphone selection
D Transmit channel high-pass filter control
D Receive channel high-pass filter control
D Companding options and selection control
D PCM loopback
D DTMF control
D Pulse density modulated control
The VBAP is also capable of generating its own internal clocks from a 2.048-MHz master clock input.
