0 C to 70 C
In the THS8133CPHP, the KIMBAL maximum specification is
assured over full temperature range and the KIMBAL(SYNC)
maximum specification is assured at 25
°
C. The position of
the blanking level is as shown in Table 1.
In the THS8133ACPHP and the THS8133BCPHP, both the
KIMBAL maximum speciffication and the KIMBAL(SYNC)
maximum specification are assured over the full temperature
range. The position of the blanking level is as shown in Table
1.
Terminal Functions
TERMINAL
I/O
DESCRIPTION
NAME
ABPb
PIN
45
O
Analog red, green and blue respectively Pr, Y and Pb current outputs, capable of directly driving a doubly
terminated 75-
coaxial cable.
AGY
41
O
ARPr
43
O
AVDD
AVSS
BLANK
40,44
I
Analog power supply (5 V
±
10%). All AVDD terminals must be connected.
Analog ground
42,46
I
23
I
Blanking control input, active low. A rising edge on CLK latches BLANK. When asserted, the ARPr, AGY and
ABPb outputs are driven to the blanking level, irrespective of the value on the data inputs. SYNC takes
precedence over BLANK, so asserting SYNC (low) while BLANK is active (low) will result in sync generation.
BPb0–BPb9
10–1
I
Blue or Pb pixel data input bus. Index 0 denotes the least significant bit. Refer to functional description for
different operating modes.
CLK
26
I
Clock input. A rising edge on CLK latches RPr0-9, GY0-9, BPb0-9, BLANK, SYNC, and SYNC_T. The M2 input is
latched by a rising edge on CLK also, but only when additional conditions are satisfied, as explained in its
terminal description.
Compensation terminal. A 0.1
μ
F capacitor must be connected between COMP and AVDD.
Digital power supply (3-V to 5-V range)
COMP

O
DVDD
DVSS
FSADJ

I

I
Digital ground
38
I
Full-scale adjust control. The full-scale current drive on each of the output channels is determined by the value of
a resistor RFS connected between this terminal and AVSS. The nominal value of RFS is 430
, corresponding to
26.67 mA full-scale current. The relationship between RFS and the full-scale current level for each operation
mode is explained in the functional description.
GY0–GY9
36–27
I
Green or Y pixel data input bus. Index 0 denotes the least significant bit. Refer to functional description for
different operating modes.
M1
47
I
Operation mode control 1. M1 is directly interpreted by the device (it is not latched by CLK). M1 configures device
according to Table 1.
M2
48
I
Operation mode control 2. The second rising edge on CLK after a transition on SYNC latches M2. The
interpretation is dependent on the polarity of the last SYNC transition:
SYNC L to H: latched as M2_INT
SYNC H to L: latched as INS3_INT
Together with M1, M2_INT configures the device as shown in Table 1. When INS3_INT is high, the sync output is
inserted on all DAC outputs; a low will insert it only on the AGY output. See also Figure 2 and Table 2. The value of
M2 at power up is undetermined. Therefore at least 1 L –>H transition on SYNC is required to set M2.
