Controllers

Micrel 10/100Base-TX MAC/PHY Controllers offer the perfect solution for adding high throughput, cost effective Ethernet connectivity to traditional non-networking processors. A wide variety of standard interface-to-Ethernet solutions are available, including PCI, SPI, 8-bit, 16-bit and 32-bit generic host processor interfaces.

Internal hardware architecture has been optimised to provide increased throughput performance, whilst reducing processor overheads and system costs. Micrel patented mixed-signal PHY technology and flexible I/O voltages ensures that the lowest power consumption is realised. In addition enhanced power management features, such as Energy Detect, Power-Down and Wake-on-LAN (WoL), further reduce power dissipation during standby and idle periods.

Typical applications:
Cable, Satellite and IP-Set Top Boxes
IP-TV
Video over IP (VoIP) and Analog Telephone Adaptors (ATA)
Audio / Video Devices
Security, Home and Building Automation
Industrial Control
Automotive Gateway and Head Unit
