Vct49x3f Py F1000 Datasheet Review
The core of the datasheet focuses on the video pipeline, which is robust for its class.
For correct operation of the vct49x3f py f1000, use the following external components:
Basic PLL Application:
[Loop Filter] → Vtune (pin1)
[3.3V Regulator] → Vcc (pin2) // with decoupling
GND → pin3
pin4 → 1000pF → [PLL Divider/Output]
Knowing where this component is used helps confirm you have the right datasheet.
If your application involves DVB-T or NTSC/PAL demodulation, the VCT49X3F is likely the first conversion stage.
A standard 28-pin or 44-pin QFP or SIP package is likely for the VCT49X3F. Here is a general mapping you’ll find in the vct49x3f py f1000 datasheet:
| Pin | Symbol | Function | | :--- | :--- | :--- | | 1 | RF IN | Antenna/Cable input (75Ω) | | 2 | AGC | RF AGC voltage input | | 3 | SDA | I²C data line | | 4 | SCL | I²C clock line | | 5 | GND | Digital ground | | 6 | VCC (3.3V) | PLL supply | | 7 | VT | Tuning voltage input (0.5-30V) | | 8 | OSC GND | Oscillator ground | | 9 | REF OSC | Reference crystal (4 MHz typical) | | 10 | IF OUT | Intermediate frequency output | | ... | ... | ... | | 28 | VCC (5V) | Analog supply |
Always refer to the official datasheet for exact pinout – an incorrect connection can destroy the delicate varactor diodes inside the tuner.
