5 / 11 page TSH94 5/11 APPLICATIONS VIDEO LINE TRANSCEIVER WITH REMOTE CONTROL PRINTED CIRCUIT LAYOUT As for any high frequency device, a few rules must be observed when designing the PCB to get the best performances from this high speed op amp. From the most to the least important points : u Each power supply lead has to be by-passed to ground with a 10nF ceramic capacitor very close to the device and 10 µF capacitor. u To provide low inductance and low resist- ance common return, use a ground plane or common point return for power and sig- nal. u All leads must be wide and as short as pos- sible especially for op amp inputs. This is in order to decrease parasitic capacitance and inductance. u Use small resistor values to decrease time constant with parasitic capacitance. u Choose component sizes as small as pos- sible (SMD). u On output, decrease capacitor load so as to avoid circuit stability being degraded which may cause oscillation. You can also add a serial resistor in order to minimise its influence. |
