MA6221-S7K Optical Mouse Controller IC
1. General Description
The MA60H22 is an encoder IC that can encode the data from the mouse optical sensor and
sends these data via RF at 27 MHZ. The MA60H22 is equipped with a complete set of FSK
modulator that also provides single/dual RF channel solution. This will reduce the extra external
component for RF interface. The two kinds of output from mouse optical sensor, namely quadrature
and SPI (serial peripheral interface) are supported. Furthermore, the MA60H22 has a DC/DC
embedded. It can work with MOSART MA606 (mouse U+P receiver controller) to be a pair of RF
www.DataSheetm4Uo.cuosme. Or it can work with MOSART MA60H13 (keyboard + mouse PS/2 receiver controller) to be
a pair of RF keyboard + mouse solution.
2. Features
z 76.8KHz clock rate (low power consumption)
z Hi speed & 32.768KHz OSC supported (optional)
z Build-in data scrambler and error detection encoder
z Build-in single/dual channel RF oscillator, modulator and power amplifier
z 4k bps Baud rate in air.
z ID change solution (256 random IDs) to resist the interference from the same
device
z 3V or 5V DC/DC embedded
z Battery low detection
z ID retention function when battery removed.
z X/Y axis support for both quadrature and SPI(serial peripheral interface) input
z Z axis supports for optical and mechanical inputs (Z/2,Z/4 can also be selected)
z Support Agilent 2000, 2030, 2051, 2610 and 2620 optical sensors.
z Support all kinds of Pixart sensors (PAN101, PAN201)
