CDCLVD1208RHDT from Texas Instruments, in a VQFN-28-EP(5x5). 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 | GND | power_in | Device ground. |
| 2 | OUTP7 | output | Differential LVDS output pair 7, positive leg, ANSI EIA/TIA-644A compatible. |
| 3 | OUTN7 | output | Differential LVDS output pair 7, negative leg, ANSI EIA/TIA-644A compatible. |
| 4 | IN_SEL | input | Input selection pin with an internal 200-kΩ pullup and pulldown; it selects the active input per Table 1 (0 = INP0/INN0, 1 = INP1/INN1), and leaving it open disables the input buffers and holds the outputs static. |
| 5 | INP1 | input | Differential redundant input pair 1, positive leg, or single-ended input. |
| 6 | INN1 | input | Differential redundant input pair 1, negative leg, or single-ended input; when used single-ended, the bias voltage VAC_REF must be applied to this unused negative input. |
| 7 | VAC_REF1 | output | Bias voltage output for capacitive-coupled inputs; if used, TI recommends a 0.1-µF capacitor to GND on this pin. |
| 8 | VCC | power_in | 2.5-V supply for the device. |
| 9 | INP0 | input | Differential input pair 0, positive leg, or single-ended input. |
| 10 | INN0 | input | Differential input pair 0, negative leg, or single-ended input; when used single-ended, the bias voltage VAC_REF must be applied to this unused negative input. |
| 11 | VAC_REF0 | output | Bias voltage output for capacitive-coupled inputs; if used, TI recommends a 0.1-µF capacitor to GND on this pin. |
| 12 | OUTP0 | output | Differential LVDS output pair 0, positive leg. |
| 13 | OUTN0 | output | Differential LVDS output pair 0, negative leg. |
| 14 | GND | power_in | Device ground. |
| 15 | VCC | power_in | 2.5-V supply for the device. |
| 16 | OUTP1 | output | Differential LVDS output pair 1, positive leg. |
| 17 | OUTN1 | output | Differential LVDS output pair 1, negative leg. |
| 18 | OUTP2 | output | Differential LVDS output pair 2, positive leg. |
| 19 | OUTN2 | output | Differential LVDS output pair 2, negative leg. |
| 20 | OUTP3 | output | Differential LVDS output pair 3, positive leg. |
| 21 | OUTN3 | output | Differential LVDS output pair 3, negative leg. |
| 22 | OUTP4 | output | Differential LVDS output pair 4, positive leg. |
| 23 | OUTN4 | output | Differential LVDS output pair 4, negative leg. |
| 24 | OUTP5 | output | Differential LVDS output pair 5, positive leg. |
| 25 | OUTN5 | output | Differential LVDS output pair 5, negative leg. |
| 26 | OUTP6 | output | Differential LVDS output pair 6, positive leg. |
| 27 | OUTN6 | output | Differential LVDS output pair 6, negative leg. |
| 28 | VCC | power_in | 2.5-V supply for the device. |
| 29 | Thermal pad (exposed pad) | passive | Exposed thermal pad that must be soldered to the printed circuit board for thermal and mechanical performance; the datasheet does not state an electrical connection for it. |
