Description
The CY2PP3115 is a low-skew, low propagation delay 1-to-15
differential fanout buffer targeted to meet the requirements of
high-performance clock and data distribution applications. 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 which are
multiplexed internally. This mux is controlled by the CLK_SEL
pin. The CY2PP3115 may function not only as a differential
clock buffer but also as a signal level translator and fanout on
ECL/PECL single-ended signal to 15 ECL/PECL differential
loads. 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 V
CC
via a 0.01-
μ
F capacitor.
Since the CY2PP3115 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 CY2PP3115 delivers consistent, guaranteed
performance over differing platforms.
