The user is free to connect another resistor value, but care should be taken not to exceed the maximum current
level on each of the DAC outputs as shown in the specifications section.
backward compatibility with the THS8133
power supply
The THS8135 is a functional superset to the THS8133 and is footprint compatible i.e. a board designed for the
THS8133 can also be used with the THS8135. Both devices come in the same package and have identical
pinouts. Only the power supply levels need to be adjusted as shown in Table 7.

device configuration
The THS8135 samples both M1 and M2 on the second rising edge of CLK after a transition on SYNC in video
modes. Depending on the polarity of the transition, M1 is interpreted as either M1_INT or BLK_INT. In the
THS8133 the M1 signal is not sampled but continuously interpreted, and is only interpreted as M1_INT. The
THS8133 does not offer a reduced-scale input code range configuration and therefore does not require
BLNK_INT.
Only when this additional functionality, which is typical for video systems, is desired, a small change in the
configuration of the device is required by supplying a dynamically changing signal on M1, generated in a similar
way as M2, as shown in Table 8.
Note that this backward compatibility is due to the selection of full-scale versus reduced-scale configurations
in Table 5. All configurations that have equal logic levels for BLNK_INT and M1_INT produce full-scale input
code range, which are compatible with the THS8133. This allows the use of a signal tied high or low on M1, as
on the THS8133, for these backward compatible full-scale configurations.
