DS15BR400TVSX from Texas Instruments, in a TQFP-48(7x7). 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 N/C unconnected No-connect pin, not connected to the device.
2 PEM input Pre-emphasis control input (LVTTL) affecting all channels: PEM = 0 turns pre-emphasis off and PEM = 1 turns it on, giving approximately 6 dB boost at 750 MHz.
3 VDD power_in Power supply, VDD = 3.3V ±10%; recommended supply range 3.0V to 3.6V.
4 VDD power_in Power supply, VDD = 3.3V ±10%; recommended supply range 3.0V to 3.6V.
5 VDD power_in Power supply, VDD = 3.3V ±10%; recommended supply range 3.0V to 3.6V.
6 N/C unconnected No-connect pin, not connected to the device.
7 VDD power_in Power supply, VDD = 3.3V ±10%; recommended supply range 3.0V to 3.6V.

10 VDD power_in Power supply, VDD = 3.3V ±10%; recommended supply range 3.0V to 3.6V.
11 VDD power_in Power supply, VDD = 3.3V ±10%; recommended supply range 3.0V to 3.6V.
12 PWDN input Active-low hardware power-down input (LVTTL) for all channels; a logic low powers down all input and output buffers and internal bias circuitry.
13 IN0+ input Channel 0 non-inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
14 IN0- input Channel 0 inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
15 IN1+ input Channel 1 non-inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
16 IN1- input Channel 1 inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
17 GND power_in Ground reference for LVDS and CMOS circuitry.
18 GND power_in Ground reference for LVDS and CMOS circuitry.
19 IN2+ input Channel 2 non-inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
20 IN2- input Channel 2 inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
21 IN3+ input Channel 3 non-inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
22 IN3- input Channel 3 inverting LVDS differential input; the DS15BR400 has an internal 100 Ω termination across the input pair and differential input voltage VID is specified from 100 mV to 2400 mV.
23 GND power_in Ground reference for LVDS and CMOS circuitry.
24 GND power_in Ground reference for LVDS and CMOS circuitry.
