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.
The FSAV433's high bandwidth and low differential gain and phase provide minimal signal distortion, high video image integrity and "transparent" switching operation.
The ultra-low-power FSAV433 is complemented by excellent off isolation and crosstalk characteristics eliminating active channel-to-channel noise and annoying ghosting effects in the display.
Moreover, the switch's low on-resistance results in minimal signal insertion loss, further increasing signal quality.
"Fairchild's FSAV433 devices are specifically designed to provide seamless switching and minimal signal routing complexity for emerging high-definition LCD systems", says Jerry Johnston, Fairchild Product Manager for Analogue Switches.
"The FSAV433 simplifies designs, reduces cost and enhances image quality".
"By replacing two traditional devices with a single three-port switch, the FSAV433 provides a more cost-effective solution for processing up to three HD video signals from DVDs, set-top boxes, PCs and other remote devices".
Key features of the FSAV433 3:1 video switch include: high bandwidth of 550MHz, -3dB; low differential gain of 0.2%, typical; low differential phase of 0.1 degree, typical; ultralow power consumption - less than 1uA; excellent off isolation of less than 75dB; superior crosstalk characteristics of -85dB; and low on-resistance, typically 6.5ohm.
Designed with full application flexibility in mind, the FSAV433 comes in a choice of 20-pin TSSOP (thin shrink small outline package) or ultracompact 20-terminal DQFN configurations.
For space-limited designs, DQFN (depopulated quad very thin flat pack no leads) is 75% smaller than TSSOP devices, runs cooler and generates lower noise and crosstalk between I/O terminals thanks to DQFN's lower capacitance and inductance.
The Pb-free FSAV433 meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with European Union requirements now in effect.
