Programmable Video Sync Generator  
’ACT715-R/LM1882-R is mask programmed to default to a  
Clock Enabled state. Bit 10 of the Status Register defaults  
to a logic ‘‘1’’. Although completely (re)programmable, the  
’ACT715-R/LM1882-R version is better suited for applica-  
tions using the default 14.31818 MHz RS-170 register val-  
ues. This feature allows power-up directly into operation,  
following a single CLEAR pulse.  
General Description  
The ’ACT715/LM1882 and ’ACT715-R/LM1882-R are  
20-pin TTL-input compatible devices capable of generating  
Horizontal, Vertical and Composite Sync and Blank signals  
for televisions and monitors. All pulse widths are completely  
definable by the user. The devices are capable of generat-  
ing signals for both interlaced and noninterlaced modes of  
operation. Equalization and serration pulses can be intro-  
duced into the Composite Sync signal when needed.

130 MHz  
Maximum Input Clock Frequency  
Four additional signals can also be made available when  
Composite Sync or Blank are used. These signals can be  
used to generate horizontal or vertical gating pulses, cursor  
position or vertical Interrupt signal.  
Interlaced and non-interlaced formats available  
Separate or composite horizontal and vertical Sync and  
Blank signals available  
Y
Complete control of pulse width via register  
programming  
These devices make no assumptions concerning the sys-  
tem architecture. Line rate and field/frame rate are all a  
function of the values programmed into the data registers,  
the status register, and the input clock frequency.

All inputs are TTL compatible  
8 mA drive on all outputs  
Default RS170/NTSC values mask programmed into  
registers  
The ’ACT715/LM1882 is mask programmed to default to a  
Clock Disable state. Bit 10 of the Status Register, Register  
0, defaults to a logic ‘‘0’’. This facilitates (re)programming  
before operation.

4 KV minimum ESD immunity  
’ACT715-R/LM1882-R is mask programmed to default  
to a Clock Enable state for easier start-up into  
14.31818 MHz RS170 timing  
The ’ACT715-R/LM1882-R is the same as the  
’ACT715/LM1882 in all respects except that the
