Multiplexing H, V and F
In ITU-R656 Mode only, SAV and EAV (H, V and F information) are multiplexed in the data.
Where data is multiplexed depends on the HD output timing.

C Bus
The TC90A58F bus control format conforms to the Philips I2C bus control format.
The two least significant bits (A0 and A1) of the slave address can be set using TES1 and TES0 (pins 79
and 80).

Countermeasure against HDIN and VDIN Pulse Noise (to avoid misinterpretation)
A countermeasure is taken to prevent spike noise in the pulse input to the HDIN and VDIN pins from
being misinterpreted as genuine HD and VD input.
The noise-detection width (either all pulses of less than 8 clocks or all pulses of less than 1 clock are
regarded as noise) can be set using the bits HDDIRECT and VDDIRECT in the I2C bus registers
Sub-Address 03H.
10. Countermeasure against VDIN Noise (to avoid misinterpretation)
A countermeasure is taken to prevent noise in 1 V (during vertical scanning) from being misinterpreted
as VD.
Noise rejection can be switched ON/OFF using the VGATEON bit in the I2C bus register Sub-Address
11H.
The noise detection range can be set using the VGTEGA and VGTEGB bits in Sub-Address 0FH~
Sub-Address 11H).
11. Internal Generation of Clamp Pulse
The clamp pulse can be internally generated.
Switching between external input and internal generation of the clamp pulse can be set using the
CLPSEL bit in the I2C bus register Sub-Address 0EH.
The clamp pulse generation timing and width can be set using the corresponding I2C bus registers.
Timing: CLPSTA10~CLPSTA4 in Sub-Address 0CH and CLPSTA3~CLPSTA0 in Sub-Address 0DH
Pulse width: CLPWID10~CLPWID7 in Sub-Address 0DH and CLPWID6~CLPWID0 in Sub-Address
0EH
