Micrel Goes The Distance, First To Market With 1.2V Output, Programmable Equalization For CML Product Family

Micrel has launched seven new products belonging to the Company's new Ultra-Low Voltage CML product family, the SY56xxx consisting of buffer, fanout buffers, multiplexer, and crosspoint switches. 

New 1.2V, 1.8V And 2.5V Ultra-Low Voltage CML Devices Power Up Data Distribution Applications With Ultra-Low Voltage

Targeted applications include data distribution for driving high-speed backplanes, rack-based equipment, Telecom/Datacom, Automatic Test Equipments, HD Video Broadcast, Data Storage, and Servers. Evaluation boards are available upon request.  Samples can now be ordered on line on Micrel's web site at:  http://www.micrel.com/ProductList.do .

All the devices come with 6.4Gbps frequency.  The SY56011R (1:2 Fanout buffer), the SY56017R (2:1 multiplexer), the SY56023R (2 x 2 Crosspoint switch), the SY56020R (1.4 Fanout buffer), and the SY56216R (dual channel buffer) come in a 3mm x 3mm, 16-pin MLF package.  The SY56034AR is a 2 x 2 Crosspoint switch with six outputs and comes in a 5mm x 5mm, 32-pin MLF package.  Finally, the SY56040AR is a 4 x 4 Crosspoint switch offered in a 7mm x 7mm, 44-pin MLF package.  All the products in this family operate up to or above 4.5GHz.

The 1.2V operation allows a power reduction of up to 50 percent.  These products can compensate for signal attenuation over long traces and backplane.  AC performance is guaranteed from DC through 6.4 Gbps, with rise and fall times less than 85ps for all products.   The product family guarantees jitter performance to be less than 10psp-p over temperature and voltage, and operation over the full industrial temperature range (-40-degC to +85-degC).  The core supply is at 2.5V, while the output power can be 1.2V, 1.8V, or 2.5V, depending upon the application.  The Equalization feature on a low voltage product gives designers a unique combination for driving inexpensive and low quality FR4 traces.  Moreover, the product family offers Micrel's patented 3-pin internal input termination, which simplifies designs and interfaces to any differential signal, AC- or DC-coupled.  The devices are offered in ultra-small MLF® packages which save critical space and improve signals.
