New from National Semiconductor, the LM4811 Boomer audio amplifier is a 105mW stereo headphone amplifier for use in 3 and 5V systems requiring a headphone output and volume control.
"Intel-based server platforms demand extensive feature sets and cost effectiveness provided by products such as National Semiconductor's PC8741x", said Barry Kennedy, senior architect for Intel's Enterprise Platforms and Services Division.
The PC8741x family provides the world's first protected concurrent access from the LPC bus and a VSB powered SMBus to all internal modules and the X-Bus extension.
The SMBus interface allows the baseboard management controller (BMC) to perform configuration and share general-purpose I/O (GPIO) with the host.
The server I/O provides an X-Bus bridge from the host interface to legacy ISA-based BMCs, for primary and alternate boot blocks, for host/BMC-shared memory, and for existing X-Bus devices that are not ported to LPC.
The server I/O economically links the host(s) with the BMC saving glue logic for advanced protection schemes while masking serial IRQ and chip select.
A VSB powered high frequency clock generator integrated into the server I/O for the BMC and its support logic lowers total system cost.
The PC8741x family offers extensive, ACPI-compliant power management support.
In addition, the PC8741x family enables extremely low current consumption in the battery backup mode, allowing longer battery life.
"National realised that servers and workstations have special requirements not met with standard Super I/O's", said Jonathan Levy, director of National's Advanced I/O Division.
"The PC8741x family of server I/Os allows our partners and customers to realise functions not possible with other Super I/O solutions.
It is the optimum I/O solution for LPC-based servers".
