TDA9884

The TDA9884 is designed as one kind of alignment-free multistandard (PAL and NTSC) vision and sound IF signal Phase-Locked Loop (PLL) demodulator device that can be used in TV, VTR, PC, and STB applications.

Features of the TDA9884 are:(1)5 V supply voltage; (2)Gain controlled wideband Vision Intermediate Frequency (VIF) amplifier, AC-coupled; (3)Gated phase detector for L and L-accent standard; (4)Digital acquisition help, VIF frequencies of 33.4 MHz, 33.9 MHz, 38.0 MHz, 38.9 MHz, 45.75 MHz and 58.75 MHz; (5)TakeOver Point (TOP) adjustable via I2C-bus or alternatively with potentiometer; (6)AM demodulator without extra reference circuit; (7)Alignment-free selective FM-PLL demodulator with high linearity and low noise; (8)Sound IF (SIF) input for single reference Quasi Split Sound (QSS) mode, PLL controlled.etc.

The absolute maximum ratings of the TDA9884 can be summarized as:(1)supply voltage: 4.5 to 5.5 V;(2)supply current: 52 to 70 mA;(3)time constant (R ´ C) for network at pin VP: 1.2 ms;(4)VIF input voltage sensitivity (RMS value): 60 to 100 uV;(5)control range VIF gain: 60 to 66 dB;(6)video output voltage (peak-to-peak value): 1.7 to 2.3 V;(7)differential phase: 2 to 4 deg;(8)-1 dB video bandwidth: 5 to 6 MHz;(9)attenuation at first sound carrier: 30 to 36 dB.
