docid023674 rev 2 7/32 HDMI2C1-14HD application information 32 figure 6. simplified view of the electrical parameters of the ddc block the hdmi ? standard specifies that the max capacitance of the cable can reach up to 700 pf. knowing that the max capacitance of the si nk input can reach up to 50 pf, this means that the i2c driver must be able to drive a load capacitance up to 750 pf. on the other hand, the i2c standard specifies a maximum rise time of the signal must be lower than 1 s in order to keep the signal integrity. taking into account the max cable capacitance of 750 pf, it is not possible to guarantee a rise time lower than 1 s in worst case. therefore, a dynamic pull-up has been integrated at the output of sda and scl lines and synchronized with the i2c driver. this signal booster accelera tes for a short period the charging time of the equivalent cable capacitance, allowing to drive any hdmi ? cable. the figure 7 illustrates the benefit of the dynamic pull-up inte grated in the hdmi 2c1-14hd device. 5v_out sda v dd_ic sda_ic v tdown_ic t rise_bus v tup_ic 70% 30% v tdown_bus v tup_bus v hyst_bus source ic drives asic side cable side sink drives through hdmi cable t fall_bus t t

docid023674 rev 2 11/32 HDMI2C1-14HD application information 32 2.4 +5v protection and fault line functional block description the +5 v power supply that the source device has to provide to the hdmi ? cable is described by the hdmi ? 2.0 standard. it must be protec ted against accidental short circuit that could occur on the cable side. the HDMI2C1-14HD device embeds a low drop current limiter. if an over-current is detected, the HDMI2C1-14HD limits the current through the +5 v power supply.if the current is too high (short circuit) , the device opens the +5 v. furthermore, the HDMI2C1-14HD device embeds also an over temperature protection (otp). if the internal temperature of the device reaches a too high value, the +5 v supply is opened in order to protect the application. in case either the curr ent limiter or the otp is triggered, the fault pin switches down to low state level (open drain topology) in order to optionally inform the hdmi ? asic that an abnormal situation has been detected (option). an under voltage lockout (uvlo) is also integr ated in the block. it checks the main +5 v power supply state, and enables the 5v_out only if the main power supply has reached a minimal value v dd_5v_on . the figure 10 shows the functional diagram of the current limiter block. figure 10. +5 v functional diagram to summarize, the short circuit protection an d the over temperature protection features are providing a high robustness level of the applicati on. on top of this, the fault line can be used in order to improve the user experience. the 5v_out pin integrates a protection against esd which is compliant with iec61000-4-2 standard, level 4 (8 kv contact). the decoupling capacitance is mandatory, according to the power management state of the art. vdd_5v +5v_out ctrl 5v fault hdmi asic or ic vdd_ic uvlo current sensor otp r pu_fault hdmi connector low drop current limiter decoupling decoupling capacitance capacitance hbm hbm iec61000-4-2 1 3 5 7 9 11 13 15 17 19 12 14 16 18 2 4 6 8 10
