PC Board Layout
The frequency response of this circuit depends greatly on the
care taken in designing the PC board.
The use of low
inductance components such as chip resistors and chip
capacitors is strongly recommended, while a solid ground
plane is a must!
Attention should be given to decoupling the power supplies.
A large value (10
μ
F) tantalum in parallel with a small value
(0.1
μ
F) chip capacitor works well in most cases.
Keep input and output traces as short as possible, because
trace inductance and capacitance can easily become the
performance limiting items.
Application Information
General
The HA4600 is a unity gain buffer that is optimized for high
performance video applications. The output disable function
makes it ideal for the matrix element in small, high input-to-
output isolation switchers and routers. This buffer contains no
feedback or gain setting resistors, so the output is a true high
impedance load when the IC is disabled (EN = 0). The HA4600
also excels as an input buffer for routers with a large number of
outputs (i.e. each input must connect to a large number of
outputs) and delivers performance superior to most video
amplifiers at a fraction of the cost. As an input buffer, the
HA4600’s low input capacitance and high input resistance
provide excellent video terminations when used with an
external 75
resistor.
Frequency Response
Most applications utilizing the HA4600 require a series
output resistor, R
S
, to tune the response for the specific load
capacitance, C
L
, driven. Bandwidth and slew rate degrade
as C
L
increases (as shown in the Electrical Specification
table), so give careful consideration to component
placement to minimize trace length. As an example, -3dB
bandwidth decreases to 160MHz for C
L
= 100pF, R
S
= 0
.
