CDCLVD1212RHAR from Texas Instruments, in a VQFN-40-EP(6x6). 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 | IN_SEL | input | Input selection pin that chooses which clock input (IN0 or IN1) is routed to the outputs; it has an internal 200-kΩ pullup and pulldown, and leaving it open disables the outputs (static). |
| 2 | INP1 | input | Positive side of the redundant differential input pair 1, which can also be used as a single-ended input; the part accepts LVDS, LVPECL, or LVCMOS inputs. |
| 3 | INN1 | input | Negative side of the redundant differential input pair 1; in single-ended operation the appropriate bias voltage VAC_REF must be applied to this unused negative input. |
| 4 | VAC_REF1 | output | Bias voltage output for capacitively coupled inputs; if used, TI recommends a 0.1-µF capacitor to GND on this pin. |
| 5 | VCC | power_in | 2.5-V device supply; recommended range is 2.375 V to 2.625 V. |
| 6 | VCC | power_in | 2.5-V device supply; recommended range is 2.375 V to 2.625 V. |
| 7 | VAC_REF0 | output | Bias voltage output for capacitively coupled inputs; if used, TI recommends a 0.1-µF capacitor to GND on this pin. |
| 8 | INN0 | input | Negative side of the differential input pair 0, which can also be used as a single-ended input with VAC_REF applied to the unused pin. |
| 9 | INP0 | input | Positive side of the differential input pair 0, which can also be used as a single-ended input; the part accepts LVDS, LVPECL, or LVCMOS inputs. |
| 10 | N.C. | unconnected | No connect; this pin is not internally connected. |
| 11 | VCC | power_in | 2.5-V device supply; recommended range is 2.375 V to 2.625 V. |
| 12 | OUTP0 | output | Positive side of LVDS differential output pair 0, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 13 | OUTN0 | output | Negative side of LVDS differential output pair 0, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 14 | OUTP1 | output | Positive side of LVDS differential output pair 1, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 15 | OUTN1 | output | Negative side of LVDS differential output pair 1, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 16 | OUTP2 | output | Positive side of LVDS differential output pair 2, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 17 | OUTN2 | output | Negative side of LVDS differential output pair 2, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 18 | OUTP3 | output | Positive side of LVDS differential output pair 3, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 19 | OUTN3 | output | Negative side of LVDS differential output pair 3, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 20 | VCC | power_in | 2.5-V device supply; recommended range is 2.375 V to 2.625 V. |
| 21 | GND | power_in | Device ground; must be connected to the thermal pad ground. |
| 22 | OUTP4 | output | Positive side of LVDS differential output pair 4, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 23 | OUTN4 | output | Negative side of LVDS differential output pair 4, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 24 | OUTP5 | output | Positive side of LVDS differential output pair 5, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 25 | OUTN5 | output | Negative side of LVDS differential output pair 5, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 26 | OUTP6 | output | Positive side of LVDS differential output pair 6, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
| 27 | OUTN6 | output | Negative side of LVDS differential output pair 6, ANSI EIA/TIA-644A compatible; the output can handle a permanent short. |
