DESCRIPTION

The CDCLVP110 clock driver distributes one

differential clock pair of either LVPECL or HSTL

(selectable) input, (CLK0, CLK1) to ten pairs of

differential LVPECL clock (Q0, Q9) outputs with minimum skew for clock distribution. The

CDCLVP110 can accept two clock sources into an

input multiplexer. The CLK0 input accepts either

LVECL/LVPECL input signals, while CLK1 accepts an

HSTL input signal when operated under LVPECL

conditions. The CDCLVP110 is specifically designed

for driving 50-Ω transmission lines.

The VBB reference voltage output is used if

single-ended input operation is required. In this case

the VBB pin should be connected to CLK0 and

bypassed to GND via a 10-nF capacitor.

However, for high-speed performance up to 3.5 GHz,

the differential mode is strongly recommended.

The CDCLVP110 is characterized for operation from

–40°C to 85°C.
