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 | VDD_DIG | power_in | Digital core supply, 1.8-3.3 V. Must be tied to the same voltage rail as VDD and VDDA. |+| 2 | CLKIN_1 | input | Clock input 1 (positive). Accepts differential or single-ended clocks; high-impedance and must be externally terminated. Selected when Input_SEL=0. |+| 3 | CLKIN_1b | input | Clock input 1 (complementary). Paired with CLKIN_1 for differential input; may be tied for single-ended use. Leave floating only if input configured as 'Unused' in ClockBuilder Pro. |+| 4 | VDD | power_in | Core supply, 1.8-3.3 V. Must be tied to same rail as VDDA and VDD_DIG. |+| 5 | NC | unconnected | No connect. Do not connect this pin to anything. |+| 6 | NC | unconnected | No connect. Do not connect this pin to anything. |+| 7 | CLKIN_2 | input | Clock input 2 (positive). Accepts differential or single-ended clocks; high-impedance and must be externally terminated. Selected when Input_SEL=1. |+| 8 | CLKIN_2b | input | Clock input 2 (complementary). Paired with CLKIN_2. Leave floating only if input configured as 'Unused' in ClockBuilder Pro. |+| 9 | VDDA | power_in | Analog core supply, 1.8-3.3 V. Must be tied to same rail as VDD and VDD_DIG. |+| 10 | Format_SEL0 | input | Output clock format selection input, LSB. Used with Format_SEL1 (pin 19) to pick differential/LVCMOS format per Section 3.2. |+| 11 | GND | power_in | Ground. Tie to system ground. |+| 12 | GND | power_in | Ground. Tie to system ground. |+| 13 | OUT0b | output | Output clock 0 (complementary). Programmable swing and common-mode; supports differential and LVCMOS formats. Leave unconnected if unused. |+| 14 | OUT0 | output | Output clock 0 (positive). Programmable swing and common-mode; supports differential and LVCMOS formats. Leave unconnected if unused. |+| 15 | VDDO0 | power_in | Output supply for OUT0 driver, 1.8-3.3 V. Sets OUT0 signal swing/format rail. Leave unconnected or tie high with driver disabled if OUT0 is unused. |+| 16 | OUT1b | output | Output clock 1 (complementary). Programmable swing and common-mode. Leave unconnected if unused. |+| 17 | OUT1 | output | Output clock 1 (positive). Programmable swing and common-mode. Leave unconnected if unused. |+| 18 | VDDO1 | power_in | Output supply for OUT1 driver, 1.8-3.3 V. Leave unconnected or tie high with driver disabled if OUT1 is unused. |+| 19 | Format_SEL1 | input | Output clock format selection input, MSB. Used with Format_SEL0 (pin 10) per Section 3.2. |+| 20 | Input_SEL | input | Input clock mux select. 0 = CLKIN_1/CLKIN_1b; 1 = CLKIN_2/CLKIN_2b. |+| 21 | OUT2b | output | Output clock 2 (complementary). Programmable swing and common-mode. Leave unconnected if unused. |+| 22 | OUT2 | output | Output clock 2 (positive). Programmable swing and common-mode. Leave unconnected if unused. |+| 23 | OUT3b | output | Output clock 3 (complementary). Programmable swing and common-mode. Leave unconnected if unused. |+| 24 | OUT3 | output | Output clock 3 (positive). Programmable swing and common-mode. Leave unconnected if unused. |+| 25 | VDDO2 | power_in | Shared output supply for OUT2 and OUT3 drivers, 1.8-3.3 V. Leave unconnected or tie high with drivers disabled if both outputs are unused. |+| 26 | NC | unconnected | No connect. Do not connect this pin to anything. |+| 27 | NC | unconnected | No connect. Do not connect this pin to anything. |+| 28 | NC | unconnected | No connect. Do not connect this pin to anything. |+| 29 | NC | unconnected | No connect.
