Preliminary specication
I2C-bus controlled BTSC stereo/SAP
decoder and audio processor
TDA9852
Notes to the characteristics
1. The oscillator is designed to operate together with MURATA resonator CSB503F58. Change of the resonator supplier
is possible, but the resonator specication must be close to CSB503F58.
2. The internal SAP carrier level is determined by the composite input level and the level adjustment gain.
3. Frequency range 20 Hz to 20 kHz; select in to input line control; effects: linear stereo.
4. Crosstalk:
5. The transmission contains:
a) Total initialization with MAD and SAD for volume and 11 DATA words, see also definition of characteristics
b) Clock frequency = 50 kHz
c) Repetition burst rate = 400 Hz
d) Maximum bus signal amplitude = 5 V (p-p).
6. The listed pin voltage corresponds with typical gain steps of +6 dB, +3 dB, 0 dB,
6 dB and 15 dB.
7. Attack time constant = CAV × Ratt.
8.
Example: CAV = 4.7 F; Idec =2 A; G1 = 9 dB; G2 =+6dB → decay time results in 4.14 s.
9. When reset is active the GMU-bit (general mute) and the LMU-bit (LINE OUT mute) is set and the I2C-bus receiver
is in the reset position.
10. The AC characteristics are in accordance with the I2C-bus specification. The maximum clock frequency is 100 kHz.
Information about the I2C-bus can be found in the brochure
“The I2C-bus and how to use it”
(order number 9398 393 40011).
