TPF1441C-VR from 3PEAK, in a MSOP-8. 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 | AIN | input | Non-inverting input of the on-chip comparator. Shares the same DC-clamp/sync-tip clamping circuit as the video input; common-mode input range is VSS+0.2 V to VDD−0.2 V. |
| 2 | NC | unconnected | No internal connection. Leave floating or tie to a static level (e.g., GND) per board convention; do not use for routing. |
| 3 | HD_OUT | output | HD composite video output from the 6th-order Butterworth low-pass filter (LPF = 72 MHz). Rail-to-rail output stage with 6 dB (2 V/V) gain capable of driving dual 75 Ω video loads AC- or DC-coupled; typical short-circuit current 65 mA. |
| 4 | +VS | power_in | Positive power supply, +3.0 V to +5.5 V single supply. Typical quiescent current is 11.5 mA at 3.3 V (15 mA at 5.0 V). Bypass locally with a low-ESR ceramic capacitor to GND. |
| 5 | HD_IN | input | HD composite video input to the 72 MHz 6th-order Butterworth reconstruction filter. Includes transparent sync-tip DC-restore clamping (VCLAMP ≈ 0 mV at IY = −100 µA) and an 80 mV level shift when DC-coupled; input impedance ~3 MΩ. |
| 6 | GND | power_in | Device ground / 0 V reference for all analog and comparator circuitry. Connect to the system ground plane with a low-impedance return. |
| 7 | DOUT | output | Comparator push-pull digital output, CMOS/TTL compatible with rail-to-rail swing (VOH ≥ VDD−0.3 V at IOUT = −1 mA; VOL ≤ VSS+0.3 V at IOUT = 1 mA). Typical propagation delay 68 ns (L→H) / 72 ns (H→L); output short-circuit current ~25 mA. |
| 8 | VREF | input | Inverting (reference) input of the on-chip comparator. Sets the comparator threshold; input offset ±3 mV max, input hysteresis typ. 6 mV. Common-mode input range VSS+0.2 V to VDD−0.2 V. |
