Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
Configurable either as a dual DPDT (double-pole/double-throw) switch or four-channel 2:1 multiplexer/demultiplexer for USB 2.0 connector sharing or port isolation, the FSUSB22 offers design engineers flexible options for various ultraportable applications.
The FSUSB22's wide bandwidth allows passage of third harmonic frequencies critical for maintaining maximum signal integrity with minimal distortion, jitter and phase noise.
Designed specifically to exceed the 240MHz minimum bandwidth requirements of the new USB 2.0 "High Speed" standard, typical FSUSB22 switching applications include next-generation cellphones, digital cameras, set-top boxes, computer games, printers, notebooks and other emerging USB 2.0 High Speed-compliant devices.

PLL clock drivers target high-speed clocking
Two low voltage PLL clock drivers designed for use in high-speed memory clocking applications are now available from Fairchild Semiconductor.
The 2.5 x 3.5mm DQFN package offers a 75% space savings over standard TSSOP packages.
The elimination of leads in the DQFN package lowers capacitance and inductance, which results in lower noise and crosstalk between the I/O terminals.
Further, the exposed die attach on the bottom of the DQFN package improves the thermal performance of the device.
Other key features of the FSUSB22 USB 2.0 analogue switch include: exceptionally wide bandwidth (above 750MHz; -3dB) ensures greater signal fidelity by minimising edge and phase distortion; less than 1uA (maximum) quiescent current consumption contributes to extended battery life; low on resistance of 5ohm (typical) reduces noise level; greater than 4kV ESD performance for human body model (HBM); and USB High Speed (480Mbit/s) and Full Speed (12Mbit/s) signalling capability.
"As the leading supplier of USB 2.0 High Speed switches, the FSUSB22 sets the standard for smaller size, lower power and wider bandwidth solutions for the emerging generation of ultraportable USB 2.0-compliant devices", said Gerald Johnston, Fairchild Product Manager for Analogue Switches.
"The FSUSB22 exemplifies Fairchild's commitment to meet the continuing demand for innovative technology solutions that provide the performance and value that OEMs need to take their ultra-portable designs to the next level".
The lead-free (Pb-free) FSUSB22 meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with European Union requirements.
