Integrated Logic Building Blocks Enable Test Equipment Manufacturers

to Reduce Component Count While Lowering Production Costs

Strengthening its leadership in precision high-speed circuits, Inphi Corporation today announced eight new very high-performance ICs for broadband test and measurement applications. These integrated devices build on the company's existing 13, 25, and 50 GHz high-speed logic (HSL) offerings and perform critical functions such as clock distribution and retiming in a variety of instrumentation systems.

"We recently selected Inphi's 1:4 clock fanout for use in our new 13.5 Gbps ParBERT (parallel bit error rate tester)," said Ingmar Bretz, Product Manager at Agilent Technologies in Boblingen, Germany. "With very low skew between channels, this part not only met our performance requirements but also enabled us to reduce the number of discrete components in our clock distribution chain and thereby lower our build costs."

With the addition of these parts to its extensive HSL product line, Inphi delivers the greatest breadth of very high-speed logic circuits available today. From D and T flip-flops and simple logic gates to data encoders, frequency dividers, and frequency multipliers, Inphi's HSL products provide the industry's best signal quality with extremely low power dissipation. This wide range of DC to 50 GHz logic components enables equipment manufacturers to develop customized systems for mid-range and high-performance markets at highly competitive price points.

1:4 Fanout

Inphi's 13726CF 1:4 fanout distributes precise clock or data signals in performance-driven applications. By packaging this functionality onto a single chip, Inphi enables test equipment manufacturers to conserve board space and reduce power levels, resulting in lower system costs. The 13726CF supports clock frequencies up to 15 GHz and data rates up to 20 Gbps and as such is ideally suited for both high-speed digital logic applications and serial data transmission systems.

2:1 Selector (as multiplexer, switch, and NRZ-to-RZ converter)

Inphi's versatile 20708SE and 20709SE 20 Gbps 2:1 selectors can function as 2:1 multiplexers, 2:1 switches, or NRZ-to-RZ converters. In test and measurement applications and automated test equipment, either of these circuits can be used as a 2:1 multiplexer to serialize two input data streams of up to 10 Gbps into a single 20 Gbps output data stream. The 20708SE or 20709SE can also be used as a 2:1 switch to select between two input data streams of up to 10 Gbps.

In optical transport systems, the 20708SE or 20709SE can operate as an RZ data generator in which an NRZ input data stream of up to 10 Gbps is converted to an RZ output data stream. As NRZ-to-RZ converters, these devices can be used to shape the RZ pulse from 20% to 80% in order to compensate for the deleterious effects of polarization mode dispersion (PMD) in the fiber. The 20708SE and 20709SE exhibit exceptionally low jitter (3 ps peak-to-peak) with fast rise and fall times (less than 25 ps).

Clock Doubler

Optimized to minimize duty cycle distortion and fundamental frequency feedthrough, Inphi's 50714CD and 50715CD clock doublers are designed for applications in which a 35 to 50 GHz clock is required from a 17.5 to 25 GHz input. For example, these parts perform the frequency doubling function in microwave instrumentation and test equipment.

Double Edge-Triggered D Flip-Flop

With its 50704DT and 50705DT double edge-triggered D flip-flops, Inphi has combined the functionality of a D flip-flop and a clock doubler in a single circuit. These devices first double the frequency of an incoming 17.5 to 20 GHz clock and then use the doubled clock to retime the data. This architecture effectively suppresses duty cycle distortion (DCD) to yield output data waveforms with very low jitter. The 50704DT and 50705DT are well suited for retiming the output of half-rate multiplexers, which often exhibit significant DCD.

Divide-by-8, Modulo-8 Counter

Inphi's divide-by-8 circuits generate a multi-phase clock signal in high-speed digital systems. The 13728DV, 25728DV, and 50728DV and the corresponding positive supply parts support clock frequencies up to 13, 25, and 50 GHz, respectively. Each device outputs differential divide-by-8 signals, thus eliminating the need to cascade two discrete circuits (a divide-by-4 and a divide-by-2). These circuits can also be used as modulo-8 counters, which simplifies module design by keeping the pin count low (one input port and one output port).
