CONFIGURATION AND CONTROL PINS | |||
VDD_SEL | 46 | S, PD | VDD Select: Configuration pin to select internal LDO regulator supply. When VDD_SEL = LOW, internal 1.1-V supply mode is selected. Feed 1.8 V to VDD18 inputs = 1.8 V ±5%. An internal 1.1-V regulator will supply the VDD11. VDD11 inputs should be terminated with bypass capacitors. When VDD_SEL = HIGH, external 1.1-V supply mode is selected. After 1.8-V supply is applied to VDD18 inputs, then apply 1.1 V 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 1.1-V supply. |
IDX | 35 | S, PD | Input. I2C

MODE | 37 | S, PD | Mode select
configuration input to set operating mode based on
input voltage level. Typically connected to voltage divider through external pullup to VDD18 and pulldown to GND. See Table 7-1. |
PDB | 30 | I, PD | Power-down
inverted Input Pin. Typically connected to processor GPIO with pull down. 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 with CSI-2 Tx outputs in tri-state. The default
function of this pin is PDB = LOW; POWER DOWN with internal 50 kΩ pull down enabled.
PDB should remain low until after power supplies are applied and reach minimum
required levels. PDB INPUT IS 3.3-V TOLERANT. See section GUID-A91AC687-C9BE-404B-9AB5-A1A04061A79E.html#GUID-A91AC687-C9BE-404B-9AB5-A1A04061A79E. PDB = 1.8 V, device is enabled (normal operation) PDB = 0, device is powered down. |

PASS = L, one or more errors were detected in the received payload. See BIST section for more information. Leave No Connect if unused. |
LOCK | 48 | O | LOCK Status: Output Pin for monitoring lock status of V3Link channel, may be used as Link Status. LOCK = H, the V3Link receiver is Locked and Rx Ports are active.
