**Texas Instruments** · LVDS ICs · VQFN-16-EP(3x3)

CDCLVD2102RGTT from Texas Instruments, in a VQFN-16-EP(3x3). 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 pin. |
| 2 | EN | input | Output control pin with an internal 200 kΩ pull-up/pull-down: logic 0 disables all outputs, open enables all outputs, and logic 1 enables OUT0/OUT1 and disables OUT2/OUT3; thresholds are VIH = 0.7×VCC and VIL = 0.2×VCC. |
| 3 | INP1 | input | Positive side of the redundant input pair 1 (INP1/INN1), accepting LVDS, LVPECL or LVCMOS clock inputs with a differential clock input frequency up to 800 MHz. |
| 4 | INN1 | input | Negative side of the redundant input pair 1 (INP1/INN1); for single-ended operation the appropriate bias voltage (VAC_REF) should be applied to this unused negative input. |
| 5 | VCC | power_in | 2.5 V device supply pin; the device supply voltage range is 2.375 V to 2.625 V. |
| 6 | INP0 | input | Positive side of the input pair 0 (INP0/INN0), accepting LVDS, LVPECL or LVCMOS clock inputs with a differential clock input frequency up to 800 MHz. |
| 7 | INN0 | input | Negative side of the input pair 0 (INP0/INN0); for single-ended operation the appropriate bias voltage (VAC_REF) should be applied to this unused negative input. |
| 8 | VAC_REF | output | Bias voltage output for capacitively coupled inputs, 1.1 V to 1.35 V (1.25 V typical) at 100 µA load with VCC = 2.5 V; a 0.1 µF capacitor to GND is recommended if used. |
| 9 | OUTP0 | output | Positive LVDS output of output pair 0, driven from input INP0/INN0, compatible with ANSI EIA/TIA-644A. |
| 10 | OUTN0 | output | Negative LVDS output of output pair 0, driven from input INP0/INN0, compatible with ANSI EIA/TIA-644A. |
| 11 | OUTP1 | output | Positive LVDS output of output pair 1, driven from input INP0/INN0, compatible with ANSI EIA/TIA-644A. |
| 12 | OUTN1 | output | Negative LVDS output of output pair 1, driven from input INP0/INN0, compatible with ANSI EIA/TIA-644A. |
| 13 | OUTP2 | output | Positive LVDS output of output pair 2, driven from input INP1/INN1, compatible with ANSI EIA/TIA-644A. |
| 14 | OUTN2 | output | Negative LVDS output of output pair 2, driven from input INP1/INN1, compatible with ANSI EIA/TIA-644A. |
| 15 | OUTP3 | output | Positive LVDS output of output pair 3, driven from input INP1/INN1, compatible with ANSI EIA/TIA-644A. |
| 16 | OUTN3 | output | Negative LVDS output of output pair 3, driven from input INP1/INN1, compatible with ANSI EIA/TIA-644A. |
| 17 | Thermal Pad | passive | Exposed thermal pad that must be soldered to the PCB with a ground-plane thermal landing pattern and multiple vias for heat removal; die temperature should be limited to a maximum of 125°C. |
