Overview

Generation of clock signal with a fixed but programmable phase difference with respect to a reference input clock is critical in many applications. An all digital DLL design with several features like wide lock range for input frequencies, short locking time, and reduced jitter is achieved by this IP.








Key features

  • Timing resolution: 80ps
  • Operating frequency range: 160MHz – 700 MHz
  • Lock time: 11 cycles
  • Generates user configurable precise phase shifts from 00 to 3600 with a resolution of 10
  • Delays multiple periodic or aperiodic signals independent of voltage and temperature.

Benefits

  • The all digital nature of the DLL design allows addition of clocking resources in FPGA prototyping of new IPs and for FPGA based embedded systems using multiple clocking resources. Rigorous simulation has been carried out to evaluate the robustness and performance of the IP. The DLL can be used for a variety of applications which require precise phase shifts with respect to reference clocks to adjust for the channel routing delays on the PCB.

Applications

  • BIST circuits for measurement of setup and hold times
  • Phase detection and tracking
  • Clock recovery from input data stream
  • High speed DDR type interface applications to align data with clock edges

Arasan’s xSPI/eMMC5.1 PHY: Unified Dual-Mode Physical Layer IP

As SoCs evolve to support a growing range of memory interfaces, designers are faced with the challenge of balancing integration complexity, pin efficiency, and performance scalability. Traditionally, implementing both xSPI (JESD251) for boot and eMMC 5.1 for high-speed storage required separate PHYs, leading to increased silicon area, power consumption, and I/O overhead.

Maximizing Performance & Reliability for Flash Applications with Synopsys xSPI Solution

Systems using SoCs designed in advanced processes generally rely on external Flash devices that use NOR/NAND Flash memory technology for non-volatile storage. NOR Flash memory offers many benefits for device manufacturers and consumers, such as faster reading, low power consumption, and smaller area. In contrast, NAND Flash memories are ideal for applications such as data storage, where higher memory capacity and faster write and erase operations are required.

The common silicon issues in analog IP integration

Despite the fears of the last decade that Moore’s Law had finally reached its end, the microelectronics sector has continued to adapt to new physical constraints and product requirements through sustained innovation and creativity. A major portion of that creative energy has gone into the development of analog, RF and mixed-signal blocks as embeddable IP.
