Chroma input (with external resistor bridge). All the switching possibilities are changed through the
BUS. Driving 75
Ω
load needs an external transistor. It is possible to have the same input connected to
several outputs. The starting configuration upon power on (power supply: 0 to 10V) is undetermined. In
this case, 6 words of 16 bits are necessary to determine one configuration. In other case, 1 word of 16
bits is necessary to determine one configuration.
12.4.2. Features
• 20MHz Bandwidth
• Cascadable with another TEA6415C (Internal address can be changed by pin 7 voltage)
• 8 Inputs (CVBS, RGB, MAC, CHROMA,...)
• 6 Outputs
• Possibility of MAC or chroma signal for each input by switching-off the clamp with an external resistor
bridge
• Bus controlled
• 6.5dB gain between any input and output
• 55dB crosstalk at 5mHz
• Fully ESD protected

12.5. SAA3010T
12.5.1. Description
The SAA3010 is intended as a general purpose (RC-5) infrared remote control system for use where a low
voltage supply and a large debounce time are expected.
The device can generate 2048 different commands
and utilizes a keyboard with a single pole switch for each key. The commands are arranged so that 32
systems can be addressed, each system containing 64 different commands. The circuit response to legal
(one key pressed at a time) and illegal (more than one key pressed at a time) keyboard operation is specified
in the section “Keyboard operation”.
12.5.2. Features
Low voltage requirement
Biphase transmission technique
Single pin oscillator
Test mode facility
