Product Highlight

  • Operating Frequency: 800 MHz
  • Operating Temp Range: -40 to +85 °C

The MCK12140 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.

When the Reference (R) and VCO (V) inputs are unequal in frequency and/or phase, the differential UP (U) and DOWN (D) outputs will provide pulse streams which when subtracted and integrated provide an error voltage for control of a VCO. The device is packaged in a small outline, surface mount 8−lead SOIC package. There are two versions of the device to provide I/O compatibility to the two existing ECL standards. The MCH12140 is compatible with MECL 10H™ logic levels while the MCK12140 is compatible to 100 K ECL logic levels. This device can also be used in +5.0 V systems.

Key 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
