DESCRIPTION
The CDCLVP1212 is a highly versatile,
low additive jitter buffer that can
generate 12 copies of LVPECL clock
outputs from one of two selectable LVPECL,
LVDS, or LVCMOS inputs for a variety of
communication applications. It has a
maximum clock frequency up to 2 GHz.
The CDCLVP1212 features an on-chip
multiplexer (MUX) for selecting one
of two inputs that can be easily
configured solely through a control pin.
The overall additive jitter performance is
less than 0.1 ps, RMS from 10 kHz to 20 MHz,
and overall output skew is as low as 25 ps,
making the device a perfect choice for use
in demanding applications.
The CDCLVP1212 clock buffer distributes one
of two selectable clock inputs (IN0, IN1) to
12 pairs of differential LVPECL clock output
(OUT0, OUT11)with minimum skew for clock
distribution. The CDCLVP1212 can accept
two clock sources into an input multiplexer.
The inputs can be LVPECL, LVDS,or LVCMOS/LVTTL.
The CDCLVP1212 is specifically designed for driving
50-Ω transmission lines. When driving the inputs in
single-ended mode, the LVPECL bias voltage
(VAC_REF) should be applied to the unused negative
input pin. However, for high-speed performance up to
2 GHz, differential mode is strongly recommended.
The CDCLVP1212 is packaged in a small 40-pin,
6-mm x 6-mm QFN package and is characterized for
operation from –40℃to +85℃.
