IF-PLL DEMODULATORS
DESCRIPTION
The SD9885 is an alignment-free multistandard (PAL and NTSC)
vision and sound IF signal PLL demodulator for negative modulation
only and FM processing.
The SD9886 is an alignment-free multistandard(PAL, SECAM and
NTSC) vision and sound IF signal PLLdemodulator for positive and
negative modulation,including sound AM and FM processing.
FEATURES
∗ 5 V supply voltage
∗ Gain controlled wide-band Vision Intermediate Frequency (VIF)
amplifier, AC-coupled
∗ Multistandard true synchronous demodulation with active
carrier regeneration
∗ 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
∗ VIF Automatic Gain Control (AGC) detector for gain control
∗ External 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
APPLICATIONS
∗ TV, VTR, PC and STB applications.
