MC44BS373CA Data Sheet
Pin Descriptions
I2C bus 3.3-V compatible
Lower power consumption in normal and standby modes (–2 mA)
Can be powered down without holding down I2C lines
TB1 bit no longer available (limited compatibility with MC44355 devices no longer available)
New SREF bit to program sound reference frequency (31.25 and 62.5 kHz)
Four different I2C addresses selectable by single pin with external resistor (available only in QFN20
package)
Direct sound RF modulator (FM and AM sound modulators bypassed) for NICAM or stereo sound
applications (available only in QFN20 package)
Switch between two integrated VCOs controlled directly by frequency divider (at 700 MHz)
Lower RF second harmonic spurious but higher third harmonic spurious. In applications it is easier
to filter UHF third harmonics spurious than second harmonics, as these frequencies are always out
of the UHF band. Unfortunately, the second harmonic can fall back into the same UHF band (for
instance channel 21 second harmonic). For this reason, it is almost impossible to have a good
rejection of low UHF second harmonic with an external low-pass filter. This is why the design has
been optimized for maximum second harmonic rejection in spite of an increase in the third
harmonic level.
