ST92R195B - 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 be used 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 is able to be made with up to
eight 8-bit PWM outputs, with a frequency maxi-
mum 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 line for data in-
put and output. A second line is used for a syn-
chronous clock signal.
1.1.11 Standard Timer (STIM)
The ST92R195B has one Standard Timer that in-
cludes a programmable 16-bit down counter and
an associated 8-bit prescaler with Single and Con-
tinuous 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
5.75µs conversion time and 6-bit guaranteed reso-
lution.
