DS90UB633ARTVRQ1

Texas Instruments · Serializers, Deserializers · WQFN-32(5x5)

DS90UB633ARTVRQ1 from Texas Instruments, in a WQFN-32(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 HSYNC input Horizontal sync input with LVCMOS levels and internal pulldown; in 10-bit mode HS is restricted to no more than one transition per 10 PCLK cycles, and it may be left open if unused.
2 VSYNC input Vertical sync input with LVCMOS levels and internal pulldown; in 10-bit mode VS is restricted to no more than one transition per 10 PCLK cycles, and it may be left open if unused.
3 PCLK input Pixel clock input with LVCMOS levels and internal pulldown; the data strobe edge is set by register 0x03[0] (TRFB).
4 SCL bidirectional Clock line of the I2C-compatible bidirectional control bus, open-drain, requiring an external pullup resistor to V(VDDIO).
5 SDA bidirectional Data line of the I2C-compatible bidirectional control bus, open-drain, requiring an external pullup resistor to V(VDDIO).
6 IDX input Analog device ID address select; a resistor (RID) to ground and a 10-kΩ pullup to the 1.8 V rail set the serializer I2C device address per table 7-6.
7 RES input Reserved pin with LVCMOS levels and internal pulldown that MUST be tied LOW.
8 MODE input Analog device mode select; a resistor to ground and a 10-kΩ pullup to the 1.8 V rail select PCLK-from-imager or external-oscillator operation per table 7-2.
9 PDB input Power-down input with LVCMOS levels and internal pulldown; PDB = H enables the serializer, and PDB = L puts it in power-down with the PLL shut down and control register data not retained.
10 VDDPLL power_in Analog PLL power supply, 1.8 V ±5%.
11 VDDT power_in Analog Tx analog power supply, 1.8 V ±5%.
12 DOUT- bidirectional Inverting CML differential output and bidirectional control channel input; the interconnect must be AC-coupled with a 0.1-µF capacitor (0.047-µF in series with 50 Ω for single-ended coax).
13 DOUT+ bidirectional Non-inverting CML differential output and bidirectional control channel input; the interconnect must be AC-coupled with a 0.1-µF capacitor.
14 VDDCML power_in Analog CML and bidirectional channel driver power supply, 1.8 V ±5%.
15 GPO[0] output General-purpose LVCMOS output that follows GPIO[0] from the deserializer or the local serializer register; leave open if unused.
16 GPO[1] output General-purpose LVCMOS output that follows GPIO[1] from the deserializer or the local serializer register; leave open if unused.
17 GPO[2]/CLKOUT output General-purpose LVCMOS output (GPIO[2] or local register) that also serves as the divided-clock output in external oscillator mode; it is recommended to pull it to GND with at least 40 kΩ to ensure LOW when PDB rises.
18 GPO[3]/CLKIN bidirectional General-purpose LVCMOS input/output (GPIO[3] or local register) that serves as the external oscillator clock input in external oscillator mode; leave open if unused.
19 DIN[0] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
20 DIN[1] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
21 DIN[2] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
22 DIN[3] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
23 DIN[4] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
24 DIN[5] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
25 VDDIO power_in I/O stage power supply for the single-ended inputs, SDA and SCL; may be 1.8 V ±5%, 2.8 V ±10%, or 3.3 V ±10%.
26 DIN[6] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
27 DIN[7] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
28 VDDD power_in Digital core power supply, 1.8 V ±5%.
29 DIN[8] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
30 DIN[9] input Parallel LVCMOS data input with internal pulldown, active in both 10-bit and 12-bit modes; unused inputs must be No Connect.
31 DIN[10] input Parallel LVCMOS data input with internal pulldown; active only in 12-bit mode and must be No Connect in 10-bit mode.
32 DIN[11] input Parallel LVCMOS data input with internal pulldown; active only in 12-bit mode and must be No Connect in 10-bit mode.
33 DAP passive Exposed pad (from the footprint; not named in the datasheet pin table).
