RSS circuitsModeling of Jitter in Bang-Bang Clock and Data Recovery Circuits
White Paper Clock and Data Recovery (CDR) circuits incorporating bang-bang (binary) Phase Detectors (PDs) have recently found wide usage. In contrast to their linear counterparts, bang-bang PDs relax the speed and precision required... [22 Oct 2008]
A Multiple-Rotating-Clock-Phase Architecture for Digital Data Recovery Circuits Using Verilog-A
White Paper This paper presents an oversampling Data Recovery (DR) architecture using Verilog-A that employs a novel Multiple-Rotating-Clock-Phase (MRCP) concept for its operation. The MRCP-DR architecture is a variant of the eye-tracking DR... [22 Oct 2008]
A Study of the Speedups and Competitiveness of FPGA Soft Processor Cores Using Dynamic Hardware/Software Partitioning
White Paper Field Programmable Gate Arrays (FPGAs) provide designers with the ability to quickly create hardware circuits. Previously, this paper proposed warp processing, a technique capable of optimizing a software application by... [22 Oct 2008]
A 1O-Gb/s CMOS Clock and Data Recovery Circuit
White Paper Clock and Data Recovery (CDR) circuits operating in the 1O-Gb/s range have become attractive for the optical fiber backbone of the Internet. While CDR circuits operating at 10-Gbls and above have been... [22 Oct 2008]
Toward Quality EDA Tools and Tool Flows Through High-Performance Computing
White Paper As the scale and complexity of VLSI circuits increase, Electronic Design Automation (EDA) tools become much more sophisticated and are held to increasing standards of quality. New-generation EDA tools must work correctly... [22 Oct 2008]
Open-Loop Clock and Data Recovery Systems
White Paper CDR circuits typically use PLLs, but their complexity presents several design challenges : the input data stream is random and is usually in Non-Return-to-Zero (NRZ) data format, and little energy exists at the clock... [22 Oct 2008]
Designing Bang-Bang PLLs for Clock and Data Recovery in Serial Data Transmission Systems
White Paper Clock recovery using Phase-Locked Loops (PLL) with binary (bang-bang) or ternary-quantized phase detectors has become increasingly common starting with the advent of fully monolithic Clock and Data Recovery (CDR)... [07 Oct 2008]
MPLS VPNs: The Real Deal
White Paper While an IPsec VPN creates a circuit across the Internet, MPLS creates circuits across service providers' networks. Are MPLS circuits less private because they aren't encrypted? Most enterprises aren't... [01 Oct 2008]
Telecom 2.0: Mind over matter
White Paper Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them. ntl:Telewest Business... [19 Sep 2008]
Medicalodges Expands Healthcare Network Capacity With Accelerators
White Paper Medicalodges had the option of going with a traditional network upgrade from 56 kbps circuits to 128 kbps or T1 speeds for several locations. Medicalodges' Wide Area Network (WAN) connects 23 skilled nursing facilities,... [19 Sep 2008]
Analyzing Switched Circuits to Design DC-DC and DC-AC Converters
