RECEIVE DATA CSI-2 OUTPUT
CSI_CLK0N 11 O RECEIVE DATA OUTPUT: This signal carries data from the FPD-LINK III Deserializer to the processor over CSI-2 interface. Receive data is CSI-2 configured with DPHY outputs as one differential clock lane (CSI_CLK0P/N) and up to four differential data lanes (CSI_D0P/N: CSI_D3P/N) or two clock lanes (CSI_CLK0P/N, CSI_CLK1P/N) and two differential data lanes for each clock. When in replicate mode data lanes CSI_D2P/N and CSI_D3P/N are associated with clock lane CSI_CLK1P/N to provide the replicated output. Leave unused outputs as no connect.

CLOCK INTERFACE
XIN/REFCLK 5 S, I Reference clock input or crystal oscillator input. Pin is shared with XIN and REFCLK. Typically REFCLK connected to 23-MHz to 26-MHz reference oscillator output (100 ppm) or XIN configured with external 23-MHz to 26-MHz crystal to XOUT. See GUID-555E6390-87D8-4557-9A5D-695BC0B61BF0.html#GUID-555E6390-87D8-4557-9A5D-695BC0B61BF0.
XOUT 4 O Crystal oscillator output: Output Pin for providing crystal oscillator reference. Leave this pin NC when reference clock input is driving XIN/REFCLK.
SYNCHRONIZATION AND GPIO
GPIO0 28 I/O, PD General-Purpose Input/Output: Pins can be used to control and respond to various commands. They may be configured to be the input signals for the corresponding GPIOs on the serializer, or they may be configured to be outputs to follow local register settings. At power up, the GPIO are disabled and include a 35-kΩ (typical) pulldown resistor by default.

An external 2-kΩ to 4.7-kΩ pullup resistor to 1.8-V or 3.3-V supply rail is recommended per I2C interface standards. I2C_SCL and I2C_SDA inputs are 3.3-V tolerant. See GUID-D33FDDF3-0FCE-4E03-B168-EFF4760CE03A.html#GUID-D33FDDF3-0FCE-4E03-B168-EFF4760CE03A for more information.
CONFIGURATION AND CONTROL PINS1.2
IDX 35 S, PD Input. I2C Serial Control Bus Primary Device ID Address Select.
Once enabled, the voltage at this pin will be sampled to configure the default I2C device address. This pin is typically connected with external pullup resistor to VDD18 and pulldown resistor to GND to create a voltage divider. See Serial Control Bus Addresses for IDX.
MODE 37 S, PD Mode select configuration input to set operating mode based on input voltage level.
This pin is typically connected to voltage divider through an external pullup to VDD18 and pulldown to GND. Table 7-2.
PDB 30 I, PD Power-down inverted Input Pin. This pin is typically connected to processor GPIO with a pulldown resistor. When PDB input is brought HIGH, the device is enabled and internal register and state machines are reset to default values. Asserting PDB signal low will power down the device and consume minimum power. The default function of this pin is PDB = LOW; POWER DOWN with internal 50-kΩ internal pulldown enabled. PDB should remain low until after power supplies are applied and reach minimum required levels. PDB INPUT IS 3.3-V TOLERANT. See GUID-EC19DD5B-2845-409C-8C7E-7905A49CF361.html#GUID-EC19DD5B-2845-409C-8C7E-7905A49CF361 for more information.
PDB = 1.8V, device is enabled (normal operation).
PDB = 0 V, device is powered down.
VDD_SEL 46 S, PD VDD Select: Configuration pin to select internal LDO regulator supply. When VDD_SEL = LOW, internal 1.1V supply mode is selected. Feed 1.8V to VDD18 inputs = 1.8V ±5%. An internal 1.1V regulator will supply the VDD11. VDD11 inputs should be terminated with bypass capacitors. When VDD_SEL = HIGH, external 1.1V supply mode is selected. After 1.8V supply is applied to VDD18 inputs, then apply 1.1V to VDD11 inputs = 1.1 V ±5%. Voltage at VDD11 supply pins must always be less than main voltage applied to VDD18 when using external 1.1V supply. VDD_SEL IS 3.3V TOLERANT.

LOCK 48 O LOCK Status: Output Pin for monitoring lock status of FPD-Link III channel that may be used for Link Status. When LOCK = H, the FPD-Link III receiver is locked and the Rx Port is active. When LOCK = L, the receiver is unlocked. See GUID-45BDD044-B57D-4058-A125-E06309E51E7B.html#GUID-45BDD044-B57D-4058-A125-E06309E51E7B for more information. Leave pin as no connect if unused.
PASS 47 O PASS Output: PASS = H indicates pass conditions are met, and PASS = L indicates that pass conditions are not met. This pin is typically routed to the processor input pin or test point for monitoring. See GUID-45BDD044-B57D-4058-A125-E06309E51E7B.html#GUID-45BDD044-B57D-4058-A125-E06309E51E7B for more information. For BIST operation, PASS = H indicates that ERROR FREE Transmission is in forward channel operation. PASS = L in BIST operation indicates that one or more errors were detected in the received payload.
