Typical Connections
Typical Connections
The chip supports MIPI output protocol. MIPI can be configured in 4-, 3- or 2-lanes.
There are no parallel data output ports.

For connectivity above:
1. All power supplies should be adequately decoupled; recommended cap values are:
• 2.8 V: 1.0 F, 0.1 F, and then 0.01 F
• 1.2 V: 1 F and 0.1 F
• 1.8 V: 0.1 F
2. Resistor value 1.5 k is recommended, but may be greater for slower two-wire speed.
3. This pull-up resistor is not required if the controller drives a valid logic level on SCLK at
all times.
4. VAA and VAA_PIX can be tied together. However, for noise immunity it is recom-
mended to have them separate (i.e. two sets of 2.8 V decoupling caps).
5. VPP, 6-7V, is used for programming OTPM. This pad is left unconnected if OTPM is not
being programmed.
6. DVDD_1V8 can be combined with VDD_IO, if VDD_IO = 1.8 V.
7. DVDD_1V2 and DVDD_1V2_PHY can be tied together.
8. ATEST1 can be left floating.
