Micrel launches 10.7-Gbit/sec universal logic gate and data-to-clock resynchronizer for communications and ATE applications

15 August 2003 San Jose, CA Lightwave -- Integrated circuit manufacturer Micrel recently unveiled two new ultra-high-speed, low jitter, precision logic devices, the SY85051U 10.7-Gbits/sec AnyGate and SY85052U Data-to-Clock Resynchronizer.

Designed using the company's Silicon Germanium process technology to meet the most stringent jitter and skew requirements for SONET/SDH OC-3 to OC-768 communications systems, the SY85051/2 are equally suitable for demanding ATE and test & measurement applications, say company representatives. The unique internal termination design included in their differential inputs allows them to easily interface to different logic standards--both AC- and DC-coupled--without any external resistor-bias and termination networks. This results in a clean, stub-free, low jitter interface.

The SY58052U is a 10.7-Gbit/sec data-to-clock resynchronizer with a guaranteed maximum data or clock throughput of 10.7 Gbits/sec or 7 GHz, respectively. The SY58052U accepts a serial data input and generates a CML output data, which is synchronized to the rising edge of the input reference clock. It is optimized for communications applications and is an ideal solution for backplane retiming or retiming after the data passes through long trace lengths.

The SY58051U is an ultra-fast, low jitter AnyGate with the same ultra-fast data and clock throughput as the SY58052U. It is capable of producing any logic functions of two Boolean variables, such as AND, NAND, OR, NOR, DELAY, or NEGATION; it can also be configured as a 2:1 MUX.

The SY58051/2U have been released to production, and pricing starts at $8.33 in 1,000-piece quantities. This family is offered in a small (3-mm x 3-mm) 16-pin MLF package and guaranteed over the -40 ° C to +85 ° C industrial temperature range. They operate from a 2.5-V or 3.3-V supply.
