CDCLVP110

SCAS683A – JUNE 2002 – REVISED AUGUST 2002

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.

PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of the Texas
Instruments standard warranty. Production processing does not
necessarily include testing of all parameters.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas
Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
