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
via a 0.01-µF 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.

Normal AC operation is obtained when the crosspoint is within the VCMR(AC) range and the input swing lies within the VPP(AC) specification. Violation of VCMR(AC) or VPP(AC) impacts the device propagation delay, device and part-to-part skew. 18. The CY2PP3115 is fully operation up to 1.5 GHz. Document #: 38-07502 Rev.*A ...
