Video Imaging Products

SIGNAL DEFINITIONS
Power
VCC and GND
+5 V power supply. All pins must be
connected.
Clock
CLK — Master Clock
The rising edge of CLK strobes all
enabled registers except for the Delay
Control Register.
Inputs
DINA11-0 — Pixel Data Input A
DINA11-0 is one of the 12-bit regis-
tered data input ports. Data is latched
on the rising edge of CLK.
DINB11-0 — Pixel Data Input B
DINB11-0 is the other 12-bit registered
data input port. Data is latched on the
rising edge of CLK.
α11-0 — Alpha Mix Input
α11-0 determines the weighting
applied to the data input signals
before being mixed together. DINA11-0
and DINB11-0 receive weightings of
α
and 1.0 –
α respectively. α11-0 is
unsigned and restricted to the range of
0 to 1.0. Figure 1 shows the data
format for
α11-0. If a value greater
than 1.0 is latched into the Alpha Mix
Input, internal circuitry will force the
value to be equal to 1.0. Data is
latched on the rising edge of CLK.
DEL — Delay Data Input
DEL is used to load the Delay Control
Register. The Delay Control Register
contains a 15-bit value which deter-
mines the number of delay stages
added to the input and control signals.
The 15-bit data value is loaded serially
into the Delay Control Register using
DEL and LD. Data present on DEL is
latched on the rising edge of LD.

Outputs
DOUT12-0 — Data Output
DOUT12-0 is the 13-bit registered data
output port.
Controls
TC — Data Format Control
TC determines if the input data is in
unsigned or two’s complement
format. If TC is LOW, the data is in
two’s complement format. If TC is
HIGH, the data is in unsigned format.
Data present on TC is latched on the
rising edge of CLK. TC only affects
the data that is being latched into the
LF48212. Changing TC does not affect
internal data already in the pipeline.
MIXEN — Alpha Mix Input Enable
When HIGH, data on
α11-0 is latched
into the LF48212 on the rising edge of
CLK. When LOW, data on
α11-0 is not
latched and the last value loaded is
held as the alpha mix value.
LD — Load Strobe
The rising edge of LD latches the data
on DEL into the Delay Control Register.
BYPASS — Bypass Delay Stage Control
The BYPASS control is used to bypass
the internal programmable delay
stages. When BYPASS is set HIGH,
the Delay Control Register will
automatically be loaded with a “0”.
This will set the number of program-
mable delay stages to zero for all
input and control signals. When
BYPASS is LOW, the desired number
of delay stages can be set by loading
RND1-0

TABLE 1.
OUTPUT ROUNDING
the Delay Control Register with the
appropriate value. Note that this
signal is not intended to change
during active operation of the
LF48212.
RND1-0 — Output Rounding Control
RND1-0 determines how the output of
the LF48212 is rounded. The output
may be rounded to 8, 10, 12, or 13-bits.
Table 1 lists the different rounding
possibilities and the associated value
for RND1-0. Rounding is accom-
plished by adding a “1” to the bit to
the right of what will become the least
significant bit. Then the bit that had
the “1” added to it and all bits to the
right of it are set to “0”. Data present
on RND1-0 is latched on the rising
edge of CLK. When RND1-0 is latched
in, it only applies to the video input
data latched in at the same time.
Changing RND1-0 does not affect the
rounding format for internal data
already in the pipeline.
OE — Output Enable
When OE is LOW, DOUT12-0 is
enabled for output. When OE is
HIGH, DOUT12-0 is placed in a high-
impedance state.
