CDCLVC1108PWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	CLKIN	input	LVCMOS clock input pin. Accepts DC to 250 MHz (3.3-V supply) or DC to 180 MHz (2.5-V supply). Minimum pulse width 1.8 ns (3.3 V) / 2.75 ns (2.5 V).
2	1G	input	Asynchronous output enable input. When 1G is low, all Y0-Y7 outputs are forced into a low state; when high, outputs follow CLKIN.
3	Y0	output	LVCMOS buffered clock output 0. Unused outputs can be left floating.
4	GND	power_in	Device ground.
5	VDD	power_in	2.5-V or 3.3-V device supply. Recommended range 3.0-3.6 V or 2.3-2.7 V; absolute max 4.6 V.
6	Y4	output	LVCMOS buffered clock output 4. Unused outputs can be left floating.
7	GND	power_in	Device ground.
8	Y6	output	LVCMOS buffered clock output 6. Unused outputs can be left floating.
9	Y7	output	LVCMOS buffered clock output 7. Unused outputs can be left floating.
10	VDD	power_in	2.5-V or 3.3-V device supply. Bypass locally with a ceramic capacitor.
11	Y5	output	LVCMOS buffered clock output 5. Unused outputs can be left floating.
12	GND	power_in	Device ground.
13	Y2	output	LVCMOS buffered clock output 2. Unused outputs can be left floating.
14	VDD	power_in	2.5-V or 3.3-V device supply. Bypass locally with a ceramic capacitor.
15	Y3	output	LVCMOS buffered clock output 3. Unused outputs can be left floating.
16	Y1	output	LVCMOS buffered clock output 1. Unused outputs can be left floating.

CAD (KiCad official)

Footprint: Package_SO:TSSOP-16_4.4x5mm_P0.65mm
3D model: TSSOP-16 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cdclvc1108pwr.step`	205 KB	You want the bare part, or you mark your own boards.
`cdclvc1108pwr-etched.step`	2.8 MB	You want the part with `CDCLVC1108PWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 693 faces against 255 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
