TVP5154 Allgemeine Beschreibung

The TVP5154 is a cutting-edge video decoder chip that offers unparalleled performance and versatility. With support for multiple video formats, including NTSC, PAL, and SECAM, it is perfectly suited for a wide range of global markets. Its integrated analog front end with a 10-bit ADC ensures exceptional video capture and processing capabilities, while the built-in analog video filters streamline the design of video processing systems, eliminating the need for external components

Hauptmerkmale

Four Separate Video Decoder Channels With Features for Each Channel:
- Accepts NTSC (M, 4.43), PAL (B,D,G,H,I,M,N) and SECAM (B, D, G, K, K1, L) Video Data
- Supports ITU-R BT.601 Standard Sampling
- High-Speed 9-Bit Analog-to-Digital Converter (ADC)
- Two Composite Inputs or One S-video Input (for Each Channel)
- Fully Differential CMOS Analog Preprocessing Channels With Clamping and Automatic Gain Control (AGC) for Best Signal to Noise (SNR) Performance
- Brightness, Contrast, Saturation, Hue, and Sharpness Control Through Inter-Integrated Circuit (I²C)
- Complementary 4-line (3-H delay) Adaptive Comb Filters for Both Cross-Luminance and Cross-Chrominance Noise Reduction
- Patented Architecture for Locking to Weak, Noisy, or Unstable Signals
Four Independent Polymorphic Scalers
Single or Concurrent Scaled and Unscaled Outputs Via Dual Clocking Data, Interleaved 54-MHz Data or Single 27 MHz-Clock
Scaled/Unscaled Image Toggle Mode Giving Variable Field Rate for Both Scaled and Unscaled Video
Low Power Consumption: 700 mW Typical
128-Pin Thin Quad Flat Pack (TQFP) Package
Single 14.31818-MHz Crystal for All Standards and All Channels
Internal Phase-Locked Loop (PLL) for Line-Locked Clock (Separate for Each Channel) and Sampling
Sub-Carrier Genlock Output for Synchronizing Color Sub-Carrier of External Encoder
Standard Programmable Video Output Format
