Preliminary specification
Audio processor for VHS hi-fi
TDA9615H
Test modes;
see Table 38
Special test modes are implemented for testing and evaluation purposes. These test modes are available via the power
byte TEST bit and selection is enabled via bits of the select byte.

X = don’t care.
Calibration may be lost when selecting product testing modes.
Audio output level for tests 25b and 25c (test output = line out) is typical
6.5 dBV (with input =
8 dBV or FM
deviation = 50 kHz; LOH = 0). Audio input level for tests 25a, 26a and 26c (test input = line in) is typical
6.5 dBV
(for output =
8 dBV or FM deviation = 50 kHz; hi-fi volume =
3 dB). The test outputs and test inputs used for
tests 25 and 26 directly connect to internal signal lines. Signals found here are not compensated for temperature or
tolerance spread, level measurements therefore can be used relative only. Absolute values are no indication of
overall performance.
Test 26c (expander test) requires the auto-normal function to be deactivated (i.e. carrier available at FMIN pin).
