Micrel introduces a range of ultra low jitter buffers

Micrel has announced the launch of eight new CML, LVPECL and LVDS buffer and multiplexer families with unique, patent-pending Failsafe Input (FSI) circuits and patented 3 Pin internal port. The new family includes the SY58603U-SY58605U4.25Gbps CML/LVPECL/LVDS buffer with fail-safe input, SY58606U-SY58608U3GHz with fail-safe input, 1:2CML/LVPECL/LVDS buffer, and fail-safe input. SY58609U-SY58611U4.25Gbps, 2:1 CML/LVPECL/LVDSMUX integrated circuit. SY58603U-SY58608U series products are currently available in volume. The SY58609U-SY58611U multiplexer will be available in December 2006. The unit price per 1000 pieces is as follows: SY58603U-SY58605U, 1.70 US dollars; SY58606U-SY58608U, 1.95 US dollars; SY58609U-SY58611U, 1.95 US dollars. A free evaluation board for all products is currently available.



The SY586xx family offers the industry's first FSI input/output protection. The chip is optimized to avoid unwanted vibration and to maintain output stability when an input signal strength change is impaired or disappears. Unlike existing LVPECL or CML buffers or multiplexers currently on the market, the SY58603-11 family avoids metastable output conditions when input signals are cancelled or signal amplitudes are faulty. This is critical for rack-based devices with many I/O cards that require hot-swap capability. The 3-pin input port simplifies the design and interface of any differential signal (with AC or DC), eliminating the need for any level switching or port resistor network in the signal path.

Thomas, vice president of high-speed bandwidth products at Micrel. Wang said: "The SY586xx series of products can solve a series of technical problems faced by designers. The company's fail-safe input (FSI) technology protects against unnecessary vibrations caused by various fault conditions during input. This is a hot-swap application. This is an ideal performance. The patented design of Micrel's internal ports is also integrated to eliminate short lines and improve signal integrity."

The new SY58603U-SY58608U fan-out buffer and the SY58609U-SY58611UMUX family minimize jitter levels to maintain signal integrity. To further improve the jitter performance of the SY58609-611U, an advanced MUX input crosstalk isolation design can be used to reduce crosstalk possibilities by up to 70%. The new buffer and MUX solution also provides AC performance to ensure clock frequency throughput up to 2.5 GHz, and LVDS and LVPECL outputs are less than 110 ps, ​​and CML outputs are less than 85 ps. It also ensures jitter of less than 10psp-p at operating temperature and voltage. The product range ensures operation over the full industrial temperature range (minus 40 degrees Celsius to 85 degrees Celsius) and ensures that the supply voltage operates from 2.5 volts to 3.3 volts. All solutions are available in MLF packages, which feature low inductance and capacitance, making the SY586xx family the ideal choice for today's high speed, low jitter designs.
