iT4131D
Description
The i T4131D is a high-speed X2 clock multiplier using 1-μm HBT Ga As 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 i T4131D can also be stimulated via NRZ data to perform edge detection. A dedicated temperature monitoring pin is also provided.
