Pin Functions
| PIN | TYPE | DESCRIPTION | |
|---|---|---|---|
| NAME | NUMBER | ||
| GND | 1, 14 | Ground | Device grounds |
| INP0, INN0 | 9, 10 | Input | Differential input pair or single-ended input. Unused input pair can be left floating. |
| INP1, INN1 | 5, 6 | Input | Redundant differential input pair or single-ended input. Unused input pair can be left floating. |
| IN_SEL | 4 | Input | Pulldown (see Pin Characteristics)
MUX select input for input choice (see Table 1) |
| OUTP7, OUTN7 | 2, 3 | Output | Differential LVPECL output pair no. 7. Unused output pair can be left floating. |
| OUTP6, OUTN6 | 26, 27 | Output | Differential LVPECL output pair no. 6. Unused output pair can be left floating. |
| OUTP5, OUTN5 | 24, 25 | Output | Differential LVPECL output pair no. 5. Unused output pair can be left floating. |
| OUTP4, OUTN4 | 22, 23 | Output | Differential LVPECL output pair no. 4. Unused output pair can be left floating. |
| OUTP3, OUTN3 | 20, 21 | Output | Differential LVPECL output pair no. 3. Unused output pair can be left floating. |
| OUTP2, OUTN2 | 18, 19 | Output | Differential LVPECL output pair no. 2. Unused output pair can be left floating. |
| OUTP1, OUTN1 | 16, 17 | Output | Differential LVPECL output pair no. 1. Unused output pair can be left floating. |
| OUTP0 OUTN0 | 12, 13 | Output | Differential LVPECL output pair no. 0. Unused output pair can be left floating. |
| VAC_REF | 7 | Output | bias voltage output for capacitive coupled inputs. Do not use VAC_REF at VCC < 3 V. If used, it is recommended to use a 0.1-μF capacitor to GND on this pin. The output current is limited to 2 mA. |
| VCC | 8, 15, 28 | Power | 2.5-/3.3-V supplies for the device |
| NC | 11 | — | Do not connect |
