MOS INTEGRATED CIRCUIT
µPD98409
ATM LIGHT SAR CONTROLLER
DESCRIPTION
The µPD98409 (NEASCOT-S40CTM) is a high-performance SAR chip for segmentation and reassembly of ATM cells. Provided with a PCI (Peripheral ponent Interconnect) bus interface control memory and supporting a MPEG packet transfer engine function to mitigate the workload of the CPU in transferring pressed image data, this chip has ideal specifications for use in a set top box (STB) to interface with an ATM network. The µPD98409 conforms to ATM Forum remendations and has AAL5-SAR sublayer and ATM layer functions.
Features
- Conforms to ATM Forum
- PCI bus interface (5/3.3 V, 32/64 bits, 33 MHz)...
