ST92195B - GENERAL DESCRIPTION
INTRODUCTION
(Cont’d)
1.1.7 Teletext, VPS and WSS Data Slicers
The three on-board data slicers using a single ex-
ternal crystal are used to extract the Teletext,VPS
and WSS information from the video signal. Hard-
ware Hamming decoding is provided.
1.1.8 Voltage Synthesis Tuning Control
14-bit Voltage Synthesis using the PWM (Pulse
Width Modulation)/BRM (Bit Rate Modulation)
technique can beused to generate tuning voltages
for TV set applications. The tuning voltage is out-
put on one of two separate output pins.
1.1.9 PWM Output
Control of TV settings can be made with up to
eight 8-bitPWM outputs, with a maximum frequen-
cy of 23,437Hz at 8-bit resolution (INTCLK = 12
MHz). Low resolutions with higher frequency oper-
ation can be programmed.
1.1.10 Serial Peripheral Interface (SPI)
The SPI bus is used to communicate with external
devices via the SPI, or I C bus communication
standards. The SPI uses a single data line for data
input and output. A second line is used for a syn-
chronous clock signal.
1.1.11 Standard Timer (STIM)
The ST92195B has one Standard Timer (STIM0)
that includes a programmable 16-bit down counter
and an associated 8-bit prescaler with Single and
Continuous counting modes.
1.1.12 Analog/Digital Converter (ADC)
In addition there is a 4-channel Analog to Digital
Converter with integral sample and hold, fast
5.75
μ
s conversion time and 6-bit guaranteed reso-
lution.
