DESCRIPTION
The CDCLVD1213 clock buffer distributes an input
clock to 4 pairs of differential LVDS clock outputs with
low additive jitter for clock distribution. The input can
either be LVDS, LVPECL, or CML.
The CDCLVD1213 contains a high performance
divider for one output (QD) which can divide the input
clock signal by a factor of 1, 2, or 4.
The CDCLVD1213 is specifically designed for driving
50 Ω transmission lines. The part supports a fail safe
function. The device incorporates an input hysteresis
which prevents random oscillation of the outputs in
the absence of an input signal.
The device operates in 2.5 V supply environment and
is characterized from –40°C to 85°C (ambient
temperature). The CDCLVD1213 is packaged in
small 16-pin, 3-mm × 3-mm QFN package.
