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.
This integration enables portable applications to handle either USB or audio signals via one connector and helps designers eliminate the need for additional components.
The FSA201 and FSA221 compact double pole/double throw (DPDT) analogue switches are especially well suited for use in popular electronic products that demand high functionality in a limited space.
Typical applications include cellphones, MP3 players, digital cameras, notebooks, LCD monitors and set-top boxes.

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.
"Fairchild's new multi-media switches tie directly to the trend in the portable market of adding more functionality into applications of the same size or even smaller", says Patty Miske, Switch Marketing Manager for Fairchild's Analog Products Group.
"For example, when used in applications like cellphones, a multimedia switch allows the phone to conveniently connect to either a headset or to a laptop using a common connector".
"Our new FSA221 switch is ideal for this application since it integrates both High-Speed USB and audio switching capability into an extremely small UMLP, while also offering best-in-class performance".
Offering the market's widest negative-swing capability (-2.0V), Fairchild's FSA201 and FSA221 switches improve system performance by enhancing signal quality, while reducing current consumption and extending battery life due to their very low on-resistance (3ohm).
Additionally, their high (10kV) ESD protection enhances system reliability.
For board space savings, the FSA201 USB 1.1 Full Speed (12Mbit/s) device is available in a 1.6 x 2.1mm MicroPak, one of the smallest packages on the market.
The FSA221 USB 2.0 High-Speed (480Mbit/s) device is also available in a UMLP (ultrathin moulded leadless package).
Measuring only 1.4 x 1.8 x 0.55mm, this remarkably compact package is 25% smaller than a MicroPak.
Additional system benefits of the FSA201 (FS) and FSA221 (HS) include: automatic Vbus detection to easily find the USB signal on plug-in of the application; user-override of Vbus detection; built in power-off protection to conserve energy; and wide bandwidth (FSA221 720MHz and FSA201 250MHz, -3dB) to ensure signal fidelity by minimising edge and phase distortion.
The FSA201 and FSA221 are lead (Pb)-free devices that meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with European Union regulations now in effect.
Samples and demo boards are available now.
