ON Semiconductor expands range of clock drivers

ON Semiconductor has expanded its range of clock drivers with the release of the NB7L585, NB7L585R, NB7V585M and NB7V586M differential 2:1 mux input to 1:6 devices.

It has also introduced the NB6HQ14M and NB7HQ14M 1:4 fan-out clock/data drivers with equalisation.

The NB6HQ14M and the NB7HQ14M integrate a selectable equaliser receiver into a differential 1:4 CML clock driver.

When placed in series with a data path operating at up to 6.5Gbit per second (Gbps) or 10Gbps, the inputs will compensate the degraded signal and output four identical CML copies of the original input signal.

The serial data rate is thereby increased by reducing the inter-symbol interference (ISI) caused by losses in the copper interconnect or long cables.

The NB7L585, the NB7L585R, the NB7V585M and the NB7V586M are the newest members of the Gigacomm range, representing a new 2:1:6 function integrating a 2:1 mux with a 1:6 fan-out buffer.

The NB7L585 and the NB7L585R are 2.5V/3.3V devices with either low-voltage positive emitter coupled logic (LVPECL) output or reduced swing emitter coupled logic (RSECL) output of 400mV peak to peak, respectively.

The NB7L585 operates up to 5GHz or 8Gbps and the NB7L585R operates up to 7GHz or 10Gbps.

The NB7V585M is an ultra-low-voltage device operating from a 1.8V/2.5V power supply.

The NB7V586M operates from an ultra-low 1.8V supply and offers the six outputs configured as three banks of two differential pairs.

Each bank of outputs has the flexibility to be powered by any combination of either 1.8V or 1.2V supplies.

Both devices operate up to clock/data rates of 6GHz/10Gbps.

These clock drivers are suitable for use in Sonet, Gigabit Ethernet, fibre-channel, backplane and other clock/data distribution applications.

The ambient operating temperature of each of these devices covers -40C to +85C.

Prices for the NB7L585, the NB7L585R, the NB7V585M, the NB7V586M, the NB6HQ14M and the NB7HQ14M start from USD5.25 (GBP3.24) in 1,000-unit quantities.

They are all offered in low-profile 3 x 3mm 16-pin or 5 x 5mm 32-pin lead-free QFN packages.

Samples are available now.
