LMH0395SQ from Texas Instruments, in a WQFN-24-EP(4x4). 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 VEE power_in Negative power supply (ground); all device voltages are referenced to VEE = 0 V.
2 VEE power_in Negative power supply (ground); all device voltages are referenced to VEE = 0 V.
3 SDI input Serial data true input, analog; common-mode range 1.65 V (VCMIN) with 720-880 mVP-P input swing at 0 m cable length.
4 SDI input Serial data complement input, analog; differential partner of pin 3.
5 VEE power_in Negative power supply (ground); all device voltages are referenced to VEE = 0 V.
6 SPI_EN input SPI register access enable (LVCMOS, internal pulldown); H selects SPI register access mode and L selects pin mode.
7 SDO1_DISABLE input Output driver 1 (SDO1, SDO1) disable (LVCMOS, internal pullup); H or no connection puts the driver in high-impedance state and L enables it.
8 AEC+ bidirectional AEC loop filter external capacitor (1-µF) positive connection; the capacitor is optional.
9 AEC- bidirectional AEC loop filter external capacitor (1-µF) negative connection; the capacitor is optional.
10 CD output Carrier detect (LVCMOS); H indicates no input signal detected and L indicates input signal detected.
11 MUTEREF input Mute reference input (analog) that sets the CD threshold and the maximum cable length equalized before muting; may be unconnected or connected to ground for normal CD operation.
12 VEE power_in Negative power supply (ground); all device voltages are referenced to VEE = 0 V.
13 SS (SPI) input SPI slave select (LVCMOS, internal pullup).
14 SDO0 output Serial data output 0 complement, LVDS; differential partner of pin 15.
15 SDO0 output Serial data output 0 true, LVDS; internally terminated 100-Ω LVDS output.
16 VEE power_in Negative power supply (ground); all device voltages are referenced to VEE = 0 V.
17 SDO1 output Serial data output 1 complement, LVDS; differential partner of pin 18.
18 SDO1 output Serial data output 1 true, LVDS; internally terminated 100-Ω LVDS output.
19 MISO (SPI) output SPI Master Input / Slave Output (LVCMOS); carries LMH0395 control data transmit.
20 VCC power_in Positive power supply, +2.5 V nominal (VCC - VEE supply range 2.375 V to 2.625 V).
21 SCK (SPI) input SPI serial clock input (LVCMOS).
22 MOSI (SPI) input SPI Master Output / Slave Input (LVCMOS, internal pulldown); carries LMH0395 control data receive.
23 VEE power_in Negative power supply (ground); all device voltages are referenced to VEE = 0 V.
24 VCC power_in Positive power supply, +2.5 V nominal (VCC - VEE supply range 2.375 V to 2.625 V).
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
