Patent ID: 7092837

Claim:
A clocking apparatus for an electronic tester, comprising: a fixed frequency clock generator that generates a first clock; a variable frequency clock generator that receives as an input the first clock from the fixed frequency clock generator and that generates a second clock; a first high speed clock generator coupled to a digital pattern generator for digital testing of a device under test, wherein the first high speed clock generator receives as an input the second clock from the variable frequency clock generator and generates a third clock having a frequency that is a first multiple of a frequency of the second clock, wherein the third clock is supplied to the digital pattern generator; a second high speed clock generator coupled to a sequenced measure system for analog testing of the device under test, wherein the second high speed clock generator receives as an input the first clock from the fixed frequency clock generator and generates a fourth clock having a frequency that is a second multiple of a frequency of the first clock, wherein the fourth clock is supplied to the sequenced measure system.
