Overview

It is a integer-N phase-locked loop frequency synthesizer (PLL) based on fully integrated 2GHz LC-VCO with low gain and fine phase noise performance. It work with reference frequency from 25 MHz XTAL oscillator or external signal source with frequency up to 500 MHz. Phase-frequency divider compare frequency can be equal or 2,3,4...63 times lower than reference. VCO frequency N-divider has programmable coefficient of division with step 1 in range 4 to 2047. Phase-frequency detector has built-in analog and digital lock detector circuits. Charge pump scheme with ADC and adjustable output current allow compensation VCO gain variation within band and keep loop gain constant. Integrated low-pass loop filter has adjustable values of resistance and capacitance for tune loop and get best phase-noise performance. All of output clocks have 0.5 duty cycle value using duty cycle recovery circuit.
The QF is designed using TSMC 65nm CRN65LP technology.

Generating multiple clock frequencies using Specman "real" feature in mixed (Analog/Digital) design environments

Using our “Specman agent approach for the Mixed Verification” along with exploiting “real” feature of Specman version 8.2, we can introduce directed/constrained randomization to the frequencies needed for the analog modules which are interacting with the DUT (Design Under Test). This approach gives complete controllability over the clock frequencies, which can be directly randomized and modified on-the-fly from the testcase, as the scenario may demand.
