detailed description
power up/reset
An external reset must be applied to the active-low RESET terminal while MCLK is active to ensure reset at
power up.
reference
A precision band-gap reference voltage is generated internally and supplies all required references to operate
the transmit and receive channels.
phase-locked loop
The phase-locked loop generates the internal clock frequency required for internal digital filters and modulators
by phase locking to 2.048-MHz master clock input.
PCM interface
The PCM interface transmits and receives data at the PCMO and PCMI terminals respectively. The data is
transmitted or received at the MCLK speed once on each PCMSYN cycle. The PCMSYN can be driven by an
external source that is derived from the master clock and used as an interrupt to the host controller.
microphone input
The microphone input circuit consists of two differential input/differential output amplifiers (MIC Amp 1 and
MIC Amp 2). MIC Amp 1 is a low-noise differential amplifier capable of an externally set gain. MIC Amp 2 is a
differential amplifier with a fixed gain of 6 dB.
analog modulator
The transmit channel modulator is a third-order sigma-delta design.
transmit filter
The transmit filter is a digital filter designed to meet Consultive Committee on International Telegraphy and
Telephony (CCITT) G.714 requirements. The TLV320AIC1107 device operates in either the 13-bit linear or 8-bit
companded A-law mode.
receive filter
The receive (RX) filter is a digital filter that meets CCITT G.714 requirements. The TLV320AIC1107 device
operates in either the 13-bit linear or 8-bit A-law companded mode, which is selected at the LINSEL input.
receive volume control
In linear mode, the three least significant bits of the 16-bit PCMI data sample is used to control volume. The
volume range is 18 dB to 3 dB in 3-dB steps.
digital modulator and filter
The second-order digital modulator and filter convert the received digital PCM data to the analog output required
by the earphone interface.
earphone amplifiers
EAROUT is recommended for use as a differential output; however, it can be connected in single-ended
topology as well. Clicks and pops are suppressed from the differential output.
