SCAS889A –OCTOBER 2009–REVISED AUGUST 2011

Eight LVPECL Output,

High-Performance Clock Buffer

Check for Samples: CDCLVP2104

FEATURES

DESCRIPTION

The CDCLVP2104 is a highly versatile, low additive

•

Dual 1:4 Differential Buffer

Two Clock Inputs

jitter buffer that can generate eight copies of LVPECL

clock outputs from two LVPECL, LVDS, or LVCMOS

inputs for a variety of communication applications. It

has a maximum clock frequency up to 2 GHz. Each

buffer block consists of one input that feeds two

LVPECL outputs. 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 15 ps,

making the device a perfect choice for use in

demanding applications.

Universal Inputs Can Accept LVPECL, LVDS,

LVCMOS/LVTTL

•

Eight LVPECL Outputs

Maximum Clock Frequency: 2 GHz

Maximum Core Current Consumption: 78 mA

Very Low Additive Jitter: <100 fs,rms in 10-kHz

to 20-MHz Offset Range

The CDCLVP2104 clock buffer distributes two clock

inputs (IN0, IN1) to eight pairs of differential LVPECL

clock outputs (OUT0, OUT7) with minimum skew for

clock distribution. Each buffer block consists of one

input that feeds two LVPECL clock outputs. The

inputs can be LVPECL, LVDS, or LVCMOS/LVTTL.

•

2.375 V to 3.6 V Device Power Supply

Maximum Propagation Delay: 450 ps

Maximum 15 ps Within Bank Output Skew

LVPECL Reference Voltage, V_{AC_REF}, Available

for Capacitive-Coupled Inputs

•

Industrial Temperature Range: –40°C to +85°C

The CDCLVP2104 is specifically designed for driving

50-Ω transmission lines. When driving the inputs in

single-ended mode, the LVPECL bias voltage

(V_{AC_REF}) should be applied to the unused negative

input pin. However, for high-speed performance up to

2 GHz, differential mode is strongly recommended.

Available in 5-mm × 5-mm QFN-28 (RHD)

Package

•

ESD Protection Exceeds 2 kV (HBM)

APPLICATIONS

The CDCLVP2104 is characterized for operation

from –40°C to +85°C and is available in a QFN-28,

5-mm × 5-mm package.
