CDCLVP110

SCAS683A – JUNE 2002 – REVISED AUGUST 2002

LOW-VOLTAGE 1:10 LVPECL/HSTL

WITH SELECTABLE INPUT CLOCK DRIVER

•

Distributes One Differential Clock Input Pair

The

CDCLVP110

clock

driver

distributes

one

LVPECL/HSTL to 10 Differential LVPECL

differential clock pair of either LVPECL or HSTL

Clock Outputs

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

differential LVPECL clock (Q0, Q9) outputs with

•

Fully Compatible With LVECL/LVPECL/HSTL

minimum

for

clock

distribution.

The

Single Supply Voltage Required,

±3.3-V or

CDCLVP110 can accept two clock sources into an

±2.5-V Supply

input multiplexer. The CLK0 input accepts either

•

Selectable Clock Input Through CLK_SEL

LVECL/LVPECL input signals, while CLK1 accepts an

HSTL input signal when operated under LVPECL

•

Low-Output Skew (Typ 15 ps) for

conditions. The CDCLVP110 is specifically designed

Clock-Distribution Applications

for driving 50-

Ω transmission lines.

VBB Reference Voltage Output for

The

VBB

voltage

output

is

used

if

Single-Ended Clocking

single-ended input operation is required. In this case

•

Available in a 32-Pin LQFP Package

the VBB pin should be connected to CLK0 and

•

Frequency Range From DC to 3.5 GHz

bypassed to GND via a 10-nF capacitor.

•

Pin-to-Pin Compatible With MC100 Series

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

EP111, ES6111, LVEP111, PTN1111

the differential mode is strongly recommended.

The CDCLVP110 is characterized for operation from

-40

°C to 85°C.
