SEMICONDUCTOR TECHNICAL DATA
Monitor On-Screen Display
CMOS
with a microcontroller unit to allow colored symbols or characters to be
displayed on a color monitor. The on–chip PLL allows both multi–system
operation and self–generation of system timing. It also minimizes the MCU’s
burden through its built–in 273 bytes display/control RAM. By storing a full
screen of data and control information, this device has a capability to carry out
‘screen–refresh’ without MCU supervision.
characters can be generated by combining two or more character blocks.
Special functions such as character bordering or shadowing, multi–level
windows, double height and double width, and programmable vertical length of
character can also be incorporated. Furthermore, neither massive information
update nor extremely high data transmission rate are expected for normal on–
screen display operation, and serial protocols are implemented in lieu of any
parallel formats to achieve minimum pin count.

... DESIGN CONSIDERATIONS Distortion Motorola’s MC141540 has a built–in PLL for multi–system application. Pin 2 voltage is dc–based for the internal VCO in the PLL. When the input frequency (HFLB) to Pin 5 in- creases, the VCO frequency will increase accordingly. This forces the PLL to a higher locked frequency output. The fre- quency should be equal to 320 x HFLB ...
