Product speciﬁcation

TV and VTR stereo/dual sound processor

with digital identiﬁcation and I²C-bus control

TDA9840

FEATURES

• Supply voltage 5 to 8 V

• De-emphasis

• Source selector

• Level and stereo matrix adjustment possible via the

I²C-bus

GENERAL DESCRIPTION

• I²C-bus transceiver

The TDA9840 is a stereo/dual sound processor for TV and

VTR sets. Its identification ensures safe operation by using

internal digital PLL technique with extremely small

bandwidth, synchronous detection and digital integration

(switching time maximum 2.3 s; identification concerning

the main functions).

• AF inputs for NICAM or AM sound (standard L)

• AF outputs for Main and SCART

• AF input and output signals selectable via the I²C-bus

• Information for identified transmission mode is readable

via I²C-bus

• Software is compatible with the TDA8415/16/17

• Quartz oscillator and clock generator

• Three digital PLL, alignment-free

• Two digital integrators, alignment-free

• Stabilizer circuit for ripple rejection and constant output

signals

• ESD protection of all pins.
