DS90UB953TRHBRQ1 from Texas Instruments, in a QFN-32-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 CSI_D1P input CSI-2 data lane 1 positive differential input with matched 100Ω (±5%) impedance; optional, can be left floating if unused.
2 CSI_D1N input CSI-2 data lane 1 negative differential input with matched 100Ω (±5%) impedance; optional, can be left floating if unused.
3 CSI_D0P input CSI-2 data lane 0 positive differential input with matched 100Ω (±5%) impedance; optional, can be left floating if unused.
4 CSI_D0N input CSI-2 data lane 0 negative differential input with matched 100Ω (±5%) impedance; optional, can be left floating if unused.
5 CSI_CLKP input CSI-2 clock positive differential input with matched 100Ω (±5%) impedance.
6 CSI_CLKN input CSI-2 clock negative differential input with matched 100Ω (±5%) impedance.
7 RES0 input Reserved pin-must be connected to ground (GND).
8 PDB input Power-down bar input with internal 1MΩ pull-down; device enabled when high (1.8V), disabled when low (0V); minimum pulse width 3ms for reset.
9 LPF1 passive Loop filter connection for PLL; typically connected to 0.022µF capacitor between this pin and VDDPLL.
10 VDDPLL_CAP passive Internal PLL regulator decoupling capacitor connection; typically connected to 10µF, 0.1µF, and 0.01µF capacitors to ground.
11 VDDPLL power_in 1.8V ±5% analog power supply for PLL; typically connected to 1µF and 0.01µF decoupling capacitors to ground.
12 LPF2 passive Loop filter connection for PLL; typically connected to 0.1µF capacitor between this pin and ground.
13 DOUT- bidirectional FPD-Link III differential output negative line; must be AC-coupled with 15-47nF capacitor to deserializer; 50Ω characteristic impedance required.
14 DOUT+ bidirectional FPD-Link III differential output positive line; must be AC-coupled with 33-100nF capacitor to deserializer; 50Ω characteristic impedance required.
15 VDDDRV_CAP passive Internal driver regulator decoupling capacitor connection; typically connected to 10µF, 0.1µF, and 0.01µF capacitors to ground.
16 VDDDRV power_in 1.8V ±5% analog power supply for driver circuits; typically connected to 1µF and 0.01µF decoupling capacitors to ground.
17 GPIO_0 bidirectional General-purpose input/output pin with 300kΩ internal pull-down; defaults to input on power-up; can be configured to detect external voltage with 3-bit ADC.
18 GPIO_1 bidirectional General-purpose input/output pin with 300kΩ internal pull-down; defaults to input on power-up; can be configured to detect external voltage with 3-bit ADC.
19 CLK_OUT/IDX bidirectional Dual-function pin: strapped at power-up as IDX to set I2C address and pull-up voltage (1.8V or 3.3V); switches to CLK_OUT after boot with minimum 35kΩ load impedance required.
20 CLKIN input Reference clock input for non-synchronous external clock mode with frequency range 25-104MHz; can be left open if using synchronous mode.
21 MODE input Mode selection strapping pin for synchronous/asynchronous/DVP modes; voltage level at power-up determines operating mode via voltage divider to VDD18/GND.
22 RES1 unconnected Reserved pin-must be left unconnected (floating); do not connect to any signal or ground.
23 I2C_SDA tri_state I2C serial data line with open-drain output; requires external pull-up resistor to 1.8V or 3.3V as determined by IDX pin configuration.
