Semtech Announces Silicon Proven 25G Ethernet Snowbush® IP Compliant with IEEE 802.3bj, CEI-25G, CEI-28G, and the Emerging IEEE 802.3bm and CAUI-4 Standards

PHY IP Platform has Characterized Silicon Measurements Demonstrating Exceptional Performance on TSMC 28nm HPM/HPC Supporting 25Gb/s and 50Gb/s Ethernet Applications

Camarillo, California - January 20, 2015

Semtech Corp(Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced silicon proven results for its Snowbush® IP analog macro operating at 25Gb/s and beyond. The new IP Platform provides lane breakouts in 2x25G (for 50Gb/s), 4x25G (for 100Gb/s) and 8x25G (for 200Gb/s) form factors.   

Big data centers are moving to upgrade their fundamental data rates with 25G+ SerDes to handle the explosion of Internet of Things (IoT) devices and large storage applications, and network solutions providers are moving toward 400Gb/s to support Zettabyte traffic. This Snowbush IP macro provides ASIC/SOC customers with the IO throughput and density needed to handle these new demands. The IP supports the recently ratified 802.3bj standard and is capable of handling electrical performance of the emerging 802.3bm and CAUI-4 standards.

“We are pleased with the excellent performance and the low power characteristics of our silicon results," said Kevin Walsh, Director of Worldwide Marketing for the Snowbush IP brand. "Semtech’s IP design teams continue to provide robust leading edge high speed PHY/SerDes IP that form the basis for developing cost-effective next generation SOC/ASIC chips. With a history of successful deliveries, the Snowbush IP brand continues its “go to” reputation." 

Features

  • Proven silicon at 25Gb/s and above on TSMC 28nm HPM/HPC
  • Support for Ethernet IEEE 802.3bj with extended reach
  • Supports a broad range of data rates from 1.25Gb/s to 28.25Gb/s
  • Numerous equalization schemes to address different channel applications and cross talk challenges
  • Automatic calibration of key circuits to maximize performance and yield
  • Robust performance with low power and low latency
  • Excellent jitter characteristics over PVT operating conditions
  • Optimized beachfront and area to meet IO throughput and density targets

About the Results

The snowPHY-C2 Platform IP is measured across PVT (Process, Voltage and Temperature) and at all supported data rates, and the detailed results are available in a characterization report. The IP is tested with a variety of backplanes and connectors. The report details the performance details for Jitter, Power and Reach. Techniques for on-chip process voltage and temperature variation detections and compensation make it possible to achieve reliable operation accounting for manufacturing variation. A summary of the silicon results is available by contacting sales@snowbush.com.

About the PHY
 
The snowPHY-C2 Platform features a full featured Analog Front End with transmit driver equalization and a receive side CTLE, AGC and DFE. Calibration of the AFE is performed via firmware control and offers customers the ability to modify the operation in a post silicon environment. A full set of test functions are supported with multiple loopback modes and PRBS generators. A “Scope-on-a-chip” Eye-monitor capability operates in a non-destructive way and provides user controlled granular adjustments for balancing speed of the eye construction with eye detail. The latency, power, area and beachfront of the IP macro are optimized to provide customers with four separate vectors of differentiation.

The snowPHY-C2 platform was developed in cooperation with Open-Silicon, Inc. They also developed a test board for measurements and characterization. 
 
Availability 
 
The snowPHY IP-C2 platform GDS is available immediately on TSMC 28nm HPM/HPC.  A reference design kit will be available in March. Pricing depends on configuration and the number of instantiations on a design. Silicon results are available for review. Contact sales@snowbush.com for additional details. Semtech offers comprehensive integration assistance, including field- and factory-based support associated with the purchase of this PHY IP. Information about the Snowbush IP family of products is available at www.semtech.com/snowbush.
