SN65LV1224BRHBT from Texas Instruments, in a VQFN-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 AVCC power_in Analog circuit power supply for the PLL and analog circuits; DVCC and AVCC must each be within 3 V to 3.6 V.
2 RI+ input Noninverting LVDS serial data input with an input threshold sensitivity of ±50 mV.
3 RI- input Inverting LVDS serial data input with an input threshold sensitivity of ±50 mV.
4 PWRDN input LVTTL input; driving it low turns off the PLL and puts the outputs into high impedance (low-power mode), and it must be held low for a minimum of 16 ns to initiate power down.
5 REN input LVTTL input; driving it low places ROUT0-ROUT9 and RCLK into the high-impedance state.
6 RCLK output LVTTL recovered clock output used to strobe ROUTx data.
7 LOCK output LVTTL output that goes low when the deserializer PLL locks onto the embedded clock edge.
8 AVCC power_in Analog circuit power supply for the PLL and analog circuits; DVCC and AVCC must each be within 3 V to 3.6 V.
9 AVCC power_in Analog circuit power supply for the PLL and analog circuits; DVCC and AVCC must each be within 3 V to 3.6 V.
10 AGND power_in Analog circuit ground for the PLL and analog circuits.
11 AGND power_in Analog circuit ground for the PLL and analog circuits.
12 DGND power_in Digital circuit ground.
13 DGND power_in Digital circuit ground.
14 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
15 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
16 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
17 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
18 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
19 DGND power_in Digital circuit ground.
20 DVCC power_in Digital circuit power supply; DVCC and AVCC must each be within 3 V to 3.6 V.
21 DGND power_in Digital circuit ground.
22 DVCC power_in Digital circuit power supply; DVCC and AVCC must each be within 3 V to 3.6 V.
23 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
24 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
25 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
26 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
27 ROUT0-ROUT9 output LVTTL parallel data output; this pin is one of the ROUT0-ROUT9 group (pins 14-18 and 23-27), with the per-bit assignment not stated in the table.
28 AGND power_in Analog circuit ground for the PLL and analog circuits.
29 AGND power_in Analog circuit ground for the PLL and analog circuits.
30 AGND power_in Analog circuit ground for the PLL and analog circuits.
31 RCLK_R/F input LVTTL input; low selects the RCLK falling-edge data strobe and high selects the rising-edge strobe.
32 REFCLK input LVTTL input that supplies the reference clock for the internal PLL frequency.
