Overview
The 24b ADC IP has a fourth-order, inherently stable, delta-sigma (??) modulator that provides good noise and linearity performance designed for the needs of industrial process control, precision instrumentation, and similar applications. The data rates are programmable up to 14.4Ksps. The digital filter can be programmed for a fast settling mode where the conversions settle in a single cycle, or programmed.

Based on the system specification of a typical smart meter, this article demonstrates the importance of carefully selecting the power metering IP solution so that its specification matches the standard requirements and copes with the application challenges. This article then pinpoints thoroughly the various issues that must be taken into account for the selection of the Silicon IP and helps identify the possible trade-offs between the performance of the Mixed-signal Front-end (MFE) and that of the Power and energy Computation Engine (PCE).
In this paper we present a methodology to model and verify a mixed-signal IP using SystemVerilog in Virtuoso and NCsim. We take our 12.5Gbps transmitter (TX) design as an example to explain the method we propose. This TX is designed to operate at programmable data rates from 1.25Gbps – 12.5Gbps and to support requirements of multiple serial protocols like USB, PCIe, and SATA. Interaction between AFE and Digital is key towards proper implementation of features like Feed Forward Equalization (FFE), programmable output swing and power management states.
Like most types of circuits, there is no such thing as a "one size fits all" PLL. This article will explore the trade-offs in PLL performance and design and look for a solution to most SOC PLL needs.
As clocks speed increase and the number of clocks increases, a programmable clock generator may offer a better system and EMI design solution
