General Description
The ’ACT715/LM1882 and ’ACT715-R/LM1882-R are 20-pin
TTL-input compatible devices capable of generating Hori-
zontal, Vertical and Composite Sync and Blank signals for
televisions and monitors. All pulse widths are completely de-
finable by the user. The devices are capable of generating
signals for both interlaced and noninterlaced modes of op-
eration. Equalization and serration pulses can be introduced
into the Composite Sync signal when needed.
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.
These devices make no assumptions concerning the system
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.
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 be-
fore operation.
The ’ACT715-R/LM1882-R is the same as the ’ACT715/
LM1882 in all respects except that the ’ACT715-R/
LM1882-R is mask programmed to default to a Clock En-
abled 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 applications using the
default 14.31818 MHz RS-170 register values. This feature
allows power-up directly into operation, following a single
CLEAR pulse.
Features
n Maximum Input Clock Frequency > 130 MHz
n Interlaced and non-interlaced formats available
n Separate or composite horizontal and vertical Sync and
Blank signals available
n Complete control of pulse width via register
programming
n All inputs are TTL compatible
n 8 mA drive on all outputs
n Default RS170/NTSC values mask programmed into
registers
n 4 KV minimum ESD immunity
n ’ACT715-R/LM1882-R is mask programmed to default to
a Clock Enable state for easier start-up into
14.31818 MHz RS170 timing
