Functional Description
The CY2DP3110 is a low-skew, low propagation delay 2-to-10
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 that are multi-
plexed internally. This mux is controlled by the CLK_SEL pin.
The CY2DP3110 may function not only as a differential clock
buffer but also as a signal-level translator and fanout on HSTL
single-ended signal to 10 ECL/PECL differential loads. An ex-
ternal 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 different self-bias point.
Since the CY2DP3110 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 com-
munication systems. Furthermore, advanced circuit design
schemes, such as internal temperature compensation, ensure
that the CY2DP3110 delivers consistent performance over
various platforms
