Figure 4 shows a detailed MT9V135 device configuration. For low-noise operation, the
MT9V135 requires separate analog and digital power supplies. Incoming digital and
analog ground conductors can be tied together next to the die.
Power supply voltages VAA (the primary analog voltage) and VAAPIX (the main voltage to
the pixel array) must be tied together to avoid current loss.
Both power supply rails should be decoupled from ground using capacitors.
The MT9V135 requires a single external voltage supply level.

Notes:
1. MT9V135 STANDBY can be connected to customer’s ASIC controller directly or to Digital
GND, depending on the controller’s capability.
2. A 1.5KΩ resistor value is recommended, but may be greater for slower (for example, 100Kb)
two-wire speed.
3. LVDS_ENABLE should be tied HIGH if LVDS is to be used.
4. Pull down DAC_REF with a 2.8K ohm resistor for 1.0V peak-to-peak video output. For a 1.4V
peak-to-peak video output, change the video resistor to 2.4K ohms.
5. VAA and VAAPIX must be tied to the same potential for proper operation.
