... BOM. To avoid any perturbation on matching from the DACs output impedance along a large band of 30MHz in HD, a discrete reconstruction filtering is implemented after the driver. This filter is matched on 75Ω . Note that the TSH344 uses a single supply architecture and it is not AC output coupled (it cannot sink an output current, therefore it is not possible to implement an output series capacitor) ...

... The delay between each video component is an important aspect in high definition video systems. To properly drive the three video components without any relative delay, the layout of the TSH344 dice has a very symmetrical geometry. this has a direct effect on the synchronization of each channel, as shown in between channels when the same V delay between the inputs and the outputs is equal to 4ns ...
