Functional Description
The CY2PP3210 is a low-skew, low propagation delay dual
1-to-5 differential fanout buffer targeted to meet the require-
ments of high-performance clock and data distribution applica-
tions. The device is implemented on SiGe technology and has
a fully differential internal architecture that is optimized to
achieve low signal skews at operating frequencies of up to 1.5
GHz.
The device features two differential input paths that are differ-
ential internally. The CY2PP3210 may function not only as a
differential clock buffer but also as a signal-level translator and
fanout distributing a single-ended signal. An external bias pin,
VBB, is provided for this purpose. In such an application, the
VBB pin should be connected to either one of the CLKA# or
CLKB# inputs and bypassed to ground via a 0.01-µF capacitor.
Traditionally, in ECL, it is used to provide the reference level
to a receiving single-ended input that might have a differential
bias point.
Since the CY2PP3210 introduces negligible jitter to the timing
budget, it is the ideal choice for distributing high frequency,
high precision clocks across back-planes and boards in
communication systems. Furthermore, advanced circuit
design schemes, such as internal temperature compensation,
ensure that the CY2PP3210 delivers consistent performance
over various platforms.
