of working in various modes from ordinary telephone voice quality to near CD quality. An
8ohm output loudspeaker driver is available for integrated handsfree use. UEME has twin
stereo codecs for stereo headsets. The audio signals are passed from Tiku in the form of
LEFT and RIGHT PDM signals plus and audio clock. The clock and PDM speed changes
according to the quality mode. UEME digital i/o voltages are 1.8V though some of the
internal logic is 2.78V. 2.78V is used for the analogue parts and VBAT is also used for
some of the driver circuits like the vibra, IHF PA, and LED driver.
The Baseband supports both internal and external microphone inputs and speaker out-
puts. Input and output source selection and gain control is performed by UEME accord-
ing to control messages from TIKU. Keypad tones, DTMF, and other AUDIO tones are
generated and encoded by TIKU and transmitted to UEME for decoding. An external vibra
alert control signal is generated by UEME with separate PWM outputs.
NMM-3 has two external serial control interfaces: FBUS and USB. FBUS can be accessed
via the test pads, and USB via the system connector.
