Description
The SV48-2.5-100-1 is an electronic component model in the IC Chips product category. It is a multistandard (PAL, SECAM and NTSC) vision and sound IF signal PLL demodulator for positive and negative modulation, including sound AM and FM processing. It also has a special function for the demodulation of FM radio signals at a frequency of 10.7 MHz.
Specifications and features
- 5 V supply voltage
- Gain controlled wide-band Vision Intermediate Frequency (VIF) amplifier, AC-coupled
- Multistandard true synchronous demodulation with active carrier regeneration: very linear demodulation, good intermodulation figures, reduced harmonics, and excellent pulse response
- Gated phase detector for L and L-accent standard
- Fully integrated VIF Voltage Controlled Oscillator (VCO), alignment-free, frequencies switchable for all negative and positive modulated standards via I2C-bus
- Digital acquisition help, VIF frequencies of 33.4, 33.9, 38.0, 38.9, 45.75, and 58.75 MHz
- 4 MHz reference frequency input: signal from Phase-Locked Loop (PLL) tuning system or operating as crystal oscillator
- VIF Automatic Gain Control (AGC) detector for gain control, operating as peak sync detector for negative modulated signals and as a peak white detector for positive modulated signals
- VIF-AGC monitor output at pin OP2
- External VIF-AGC setting via pin OP1
- Precise fully digital Automatic Frequency Control (AFC) detector with 4-bit digital-to-analog converter, AFC bits readable via I2C-bus
- TakeOver Point (TOP) adjustable via I2C-bus or alternatively with potentiometer
- Fully integrated sound carrier trap for 4.5, 5.5, 6.0, and 6.5 MHz, controlled by FM-PLL oscillator
- Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode, PLL controlled
- SIF-AGC for gain controlled SIF amplifier, single reference QSS mixer able to operate in high-performance single reference QSS mode and in intercarrier mode, switchable via I2C-bus
- AM demodulator without extra reference circuit
- Alignment-free selective FM-PLL demodulator with high linearity and low noise
- I2C-bus control for all functions
- I2C-bus transceiver with pin programmable Module Address (MAD)
- Four selectable I2C-bus addresses
- SIF and FM-AGC for radio (optional)
- Radio IF (RIF) input using the sound IF SAW input for converting to 10.7 MHz, input frequencies are 41.3 MHz for NTSC (M/N standard) applications and 33.3 MHz for other applications
- Alignment-free FM radio demodulation at 10.7 MHz
- Radio AFC
- External FM input and demodulation
Application Scenarios
The SV48-2.5-100-1 is suitable for use in TV, VTR, PC, and STB applications.
