APPLICATION NOTE

Differential Input and Output Considerations
The CLC5506 typical application requires DC blocking ca-
pacitors for both inputs and outputs to main internal DC bias-
ing points.
The input impedance between the differential inputs (IN+,
IN-) is 200
//0.5pF. Since the 0.5pF capacitance can be ne-
glected in the VHF band, a 1:4 impedance ratio balun can be
used to transform a 50
source to the 200
differential in-
puts of CLC5506 for wide band design.
The CLC5506 has a pair of open collector differential outputs
(OUT+, OUT-). DC biasing is achieved through an RF induc-
tor. The RF inductor acts as a choke to block RF leakage and
interference. An external resistor across the differential out-
puts is used to set the output resistance of CLC5506. Wide-
band output matching to an unbalanced 50
load can be
achieved by using a 1:n balun. A 1:4 impedance ratio balun
is used when a 200
external resistor is used in a 50
sys-
tem.
Although the CLC5506 can be used as a single-ended de-
vice by grounding one of the inputs through a capacitor, the
noise figure would be severely degraded by 6dB.
The CLC5506 can also directly interface to balanced de-
vices, like SAW filters and ADCs. Narrowband design ex-
ample with ADC CLC5956 and SAW filter is provided below.
The component values of matching inductors and capacitors
depend on the actual input/output impedance of the SAW fil-
ter, ADC, PWB properties, layout and frequency band.
CLC5506 Evaluation Board
A proper printed circuit layout is essential for achieving high
frequency performance. To expedite evaluation, an as-
sembled and tested evaluation kit CLC5506PCASM is avail-
able for sale. See application note AN-1138 for technical de-
tails of evaluation kit. Order information and application note
is available on the Web at http://www.national.com
