V50000007 datasheet(5/63 Pages) TOSHIBA

5 / 63 page

Features:

n 5V supply voltage; low power consumption

n Active carrier generation by FPLL principle (frequency-phase-locked-loop) for true synchronous demodulation

n Very linear video demodulation, good pulse response and excellent intermodulation figures

n VCO circuit is operating on picture carrier frequency, the VCO frequency is switchable for the L mode

n Alignment-free AFC without external reference circuit, polarity of the AFC curve is switchable

n VIF-AGC for negative modulated signals (peak sync detection) and for positive modulation

(peak white/black level detector).

n Tuner AGC with adjustable take over point

n Alignment-free quasi parallel sound (QPS) mixer for FM/NICAM sound IF signals

n Intercarrier output signal is gain controlled (necessary for digital sound processing)

n Complete alignment-free AM demodulator with gain controlled AF output

n Separate SIF-AGC with average detection

n Two independent SIF inputs

n Parallel operation of the AM demodulator and QPS mixer (for NICAM-L stereo sound)

n Package and relevant pinning is compatible with the single standard version TDA 4472; simplifies the design of

an universal IF module

TUNER

The hardware and software of the TV is suitable for tuners, supplied by different companies, which are selected from the

Service Menu. These tuners can be combined VHF, UHF tuners suitable for CCIR systems B/G, H, L, L´, I/I´, and D/K.

The tuning is available through the digitally controlled I²C bus (PLL). Below you will find info on one of the Tuners in use.

General description of UV1316:

The UV1316 tuner belongs to the UV 1300 family of tuners, which are designed to meet a wide range of applications. It is a

combined VHF, UHF tuner suitable for CCIR systems B/G, H, L, L, I and I. The low IF output impedance has been designed

for direct drive of a wide variety of SAW filters with sufficient suppression of triple transient.

Features of UV1316:

n Member of the UV1300 family small sized UHF/VHF tuners

n Systems CCIR: B/G, H, L, L, I and I; OIRT: D/K

n Digitally controlled (PLL) tuning via I2C-bus

n Off-air channels, S-cable channels and Hyperband

n World standardised mechanical dimensions and world standard pinning

n Compact size

n Complies to CENELEC EN55020 and EN55013
