iT4134D
X2, 4-to-7 GHz Clock Multiplier
(Advanced Information)
Description
www.DataSheet4U.com
The iT4134D is a high-speed X2 clock multiplier fabricated using 1-μm HBT GaAs technology
and employs an ECL topology to guarantee high-speed operation. It is an excellent choice for
digital clock multiplication, instrumentation, and edge detection. Digital clock multiplication is
implemented via XOR operation between the input clock and an internal delayed replica. Several
embedded electrically-controlled phase delays are also employed. Suitable regulation of the
phase delay voltage controls allows duty cycle control on the clock outputs. Suitable power
supply internal distribution provides the ability to disable the echo input which reduces power
consumption. The iT4134D can also be stimulated via NRZ data to perform edge detection. A
dedicated temperature monitoring pin is also provided.
