Description

The MCH/K12140 is a phase frequency−detector intended for phase−locked loop applications which require a minimum amount of phase and frequency difference at lock. When used in conjunction with high performance VCO such as the MC100EL1648, a high bandwidth PLL can be realized. The device is functionally compatible with the MC12040 phase−frequency detector with the maximum frequency extending to 800 MHz.

Features

• 800 MHz Typical Bandwidth

• Small Outline 8-Lead SOIC Package

• 75 kΩ Internal Input Pulldown Resistors

• >1000 V ESD Protection

• Pb−Free Packages are Available

For proper operation, the input edge rate of the R and V inputs should be less than 5.0 ns.
