Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
The devices are offered in several package options, including RoHS-compliant lead-free, plastic dual-inline packages (PDIP).
The Avago HCTL-20xx series ICs feature 14MHz clock speed and are designed to improve system performance in digital closed loop motion control systems and digital data input systems by shifting time-intensive quadrature decoder functions from software on a microprocessor to a cost-effective hardware solution.
The ICs are used to interface rotary or linear quadrature incremental encoders to microprocessors and to interface digital potentiometers to digital data input buses.

IR transceiver slims down to fit latest PDAs
Agilent Technologies has announced a new serial infra-red (SIR) transceiver that is ideal for new-generation personal information devices, such as PDAs, which are becoming increasingly thinner.
"The new HCTL-20xx series ICs are drop-in replacements for our popular HCTL-2000, HCTL-2016 and HCTL-2020 devices", said Chong Khin Mien, Vice President for the Motion Control Products Division at Avago Technologies.
"They offer much higher frequency for improved system performance and are available in environmental friendly RoHS-compliant packages".
The HCTL-20xx series ICs include quadrature decoder logic, a binary up/down state counter, and an 8bit bus interface.
The use of Schmitt-triggered CMOS inputs and input noise filters provides reliable operation in noisy environments.
The ICs are available in the following versions.
The HCTL-2001-A00 is a 12bit counter/quadrature decoder available in a low-profile dual-inline on PCB package (LP) and in a lead-free PDIP.
The HCTL-2017-A00 is a 16bit counter/quadrature decoder available in the LP package, plastic leaded chip carrier (PLCC) and lead-free PDIP.
The HCTL-2021-A00 is a 16bit counter/quadrature decoder available in the LP, PLCC, and lead-free PDIP packages.
It provides quadrature decoder output signals and a cascading capability that allows for position reads of more than 2byte by latching all the bytes and then reading the bytes sequentially over the 8bit bus.
This permits the HCTL-2021 to interface with many standard computer ICs.
The Avago HCTL-20xx series ICs are available now in sample and production quantities through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
