TSH7x Testing conditions 4 Testing conditions 4.1 Layout precautions To use the TSH7X circuits in the best manner at high frequencies, some precautions have to be taken for power supplies: • First of all, the implementation of a proper ground plane on both sides of the PCB is mandatory for high-speed circuit applications to provide low inductance and low resistance common return. • Power supply bypass capacitors (4.
Testing conditions 4.2 TSH7x Maximum input level Figure 47. CCIR330 video line The input level must not exceed the following values: • Negative peak: must be greater than -VCC+400 mV • Positive peak value: must be lower than +VCC-400 mV The electrical characteristics show the influence of the load on this parameter. 4.3 Video capabilities To characterize the differential phase and differential gain, a CCIR330 video line is used.

Testing conditions 4.4 TSH7x Precautions when operating on an asymmetrical supply The TSH7X can be used with either a dual or a single supply. If a single supply is used, the inputs are biased to the mid-supply voltage (+VCC/2). This bias network must be carefully designed, in order to reject any noise present on the supply rail. As the bias current is 15 µA, you must carefully choose the resistance R1 so as not to introduce an offset mismatch at the amplifier inputs. Figure 49.
