FEATURES  
DESCRIPTION  
The CDCLVP1208 is a highly versatile, low additive  
jitter buffer that can generate eight copies of LVPECL  
clock outputs from one of two selectable LVPECL,

•
2:8 Differential Buffer  
Selectable Clock Inputs Through Control Pin  
Universal Inputs Accept LVPECL, LVDS, and  
LVCMOS/LVTTL  
LVDS, or LVCMOS inputs for  
a
variety of  
communication applications. It has a maximum clock  
frequency up to 2 GHz. The CDCLVP1208 features  
an on-chip multiplexer (MUX) for selecting one of two  
inputs that can be easily configured solely through a  
control pin. 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 20 ps, making the  
device a perfect choice for use in demanding  
applications.

Maximum Propagation Delay: 450 ps  
Maximum Output Skew: 20 ps  
The CDCLVP1208 clock buffer distributes one of two  
selectable clock inputs (IN0, IN1) to eight pairs of  
differential LVPECL clock outputs (OUT0, OUT7) with  
minimum skew for clock distribution. The  
CDCLVP1208 can accept two clock sources into an  
input multiplexer. The inputs can be LVPECL, LVDS,  
or LVCMOS/LVTTL.  
LVPECL Reference Voltage, VAC_REF, Available  
for Capacitive-Coupled Inputs

•
•
Industrial Temperature Range: –40°C to +85°C  
ESD Protection Exceeds 2 kV (HBM)  
Available in 5-mm × 5-mm QFN-28 (RHD)  
Package  
The CDCLVP1208 is specifically designed for driving  
50-Ω transmission lines. When driving the inputs in  
single-ended mode, the LVPECL bias voltage  
(VAC_REF) should be applied to the unused negative  
input pin. However, for high-speed performance up to  
2 GHz, differential mode is strongly recommended.  
APPLICATIONS

Wireless Communications  
Telecommunications/Networking  
Medical Imaging  
The CDCLVP1208 is packaged in a small 28-pin,  
5-mm x 5-mm QFN package and is characterized for  
operation from –40°C to +85°C.
