The complete part number contains specific information about the device’s packaging and firmware:
Based on the datasheet and technical profiles, here is a deep dive into its core capabilities: Integrated Architecture: vct49x3f py f1000 datasheet
If you're dealing with a faulty TV that uses this component, knowing that it's a DVP-86 package and looking for the "PY F1000" suffix is key. Need to check availability or verify a compatible version? VCT49X3F-PY-F-1000 MICRONAS DIP86 Other Components
When ordering a replacement part, matching "VCT49X3F" is insufficient. The suffix designates the specific mask set, internal ROM firmware revision, and hardware packaging configuration. Installing a variant with a different suffix (e.g., "PZ F1000") will result in an incompatible I2C structure, causing a blinking standby light and a failure to turn on.

Capable of operating at frequencies up to 1GHz for superior signal clarity. Compliance: Fully Lead-free and RoHS compliant . Primary Functions & Applications
Often utilized as a "virgin" chip for Samsung television and video systems.
This is highly likely a 1 GHz Voltage-Controlled Oscillator (VCO) in a miniature 4.9mm x 3.8mm package, possibly with a 3.3V supply and extended temperature range. PY = 2025
QFP-88 (Quad Flat Package, 88 pins) or PMIP-88 depending on the specific chassis revision.
A graph showing VT (volts) vs. RF frequency (MHz) is essential for software developers. Without this curve from the , you cannot calculate the correct N-divisor for the PLL.
Without the official , we can infer typical specs from similar voltage-controlled tuner ICs (e.g., Sharp VA3T1B, Philips TDA665x, or Samsung VCT series). Use this as a pre-datasheet checklist.
