Press Release Summary:
Featuring 3-pin internal termination, series SY586xx of CML, LVPECL, and LVDS buffers and multiplexers, simplifies designs and interfaces to any differential signal, ac- or dc-coupled, without any level shifting or termination resistor networks in signal path. Ultra-low jitter units are available in MLFÂ® packaging, and prevent metastable output condition in hot swap applications when input signal is removed or signal amplitude fails.
Original Press Release:
Micrel Announces Industry's First 4.25 Gbps, Ultra-Low Jitter Buffer and MUX Family with Fail Safe I/O Protection
New Solutions Prevent Output Errors in Hot Swap Applications
SAN JOSE, Calif., Nov. 10 /-- Micrel Inc., (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched a family of eight new CML, LVPECL, and LVDS buffers and multiplexers that feature unique, patent-pending Fail Safe Input (FSI) circuitry and patented 3-pin internal termination. The new series includes the SY58603U-SY58605U 4.25Gbps CML/LVPECL/LVDS buffers with Fail Safe Input; the SY58606U-SY58608U 3GHz, 1:2 CML/LVPECL/LVDS buffers with Fail Safe Input and the SY58609U-SY58611U 4.25Gbps, 2:1 CML/LVPECL/LVDS MUX ICs with Fail Safe Input. The SY58603U-SY58608U series is currently available in volume quantities. The SY58609U-SY58611U multiplexers will be available in December 2006. Prices for 1K quantities are as follows: the SY58603U-SY58605U: $1.70; the SY58606U-SY58608U: $1.95; and the SY58609U-SY58611U: $1.95. Free evaluation boards for all parts are available.
The SY586xx series offer the industry's first FSI I/O protection. The chips are optimized to prevent unwanted oscillations and maintain output stability when an input signal's swing collapses or disappears. Unlike existing LVPECL or CML buffers or multiplexers currently on the market, the SY58603-11 family prevents a metastable output condition when the input signal is removed or signal amplitude fails. This is especially crucial for rack-based equipment that has many I/O cards requiring Hot Swap capability. The 3-pin input termination simplifies designs and interfaces to any differential signal, AC- or DC-coupled, without any level shifting or termination resistor networks in the signal path.
"The SY586xx series addresses a number of technical challenges for designers," said Thomas S. Wong, vice president high bandwidth products, Micrel. "The Company's Fail Safe Input (FSI) technology protects unwanted oscillations due to various fault conditions at the inputs. This is an ideal feature for Hot Swap applications. Micrel's proprietary design for internal termination is also incorporated to eliminate stubs and improve signal integrity."
The new SY58603U-SY58608U fanout buffers and SY58609U-SY58611U MUX series minimize jitter to preserve signal integrity. To further improve the jitter performance of SY58609-611U, a superior MUX input cross talk isolation design is implemented that reduces crosstalk by up to 70 percent. The new solutions of buffers and MUXes also offer AC performance that guarantees clock frequency throughput up to 2.5GHz, and rise and fall times less than 110ps for LVDS and LVPECL outputs and less than 85ps for CML outputs. Jitter performance is guaranteed to be less than 10psp-p over temperature and voltage. The product family guarantees operation over the full industrial temperature range (-40C to +85C) and supply voltage operation from 2.5V to 3.3V. All solutions are available in MLF® packaging which features low inductance and capacitance, making the SY586xx series ideal for today's high-speed, low jitter designs.
