DESCRIPTION
The µPD98409 (NEASCOT-S40CTM) is a high-performance SAR chip for segmentation and reassembly of ATM cells. Provided with a PCI (Peripheral Component Interconnect) bus interface control memory and supporting a MPEG packet transfer engine function to mitigate the workload of the CPU in transferring compressed 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 recommendations 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)
Conforms to PCI Local Bus Specification Revision 2.1
• AAL-5 SAR sublayer and ATM layer functions
• Hardware support of AAL-5 processing (non-AAL-5 processing can be supported in software)
• Supports up to 64 virtual channels (VC) (64-VC control memory)
• Two traffic shapers for transmission scheduling
• MPEG packet transfer engine mitigating the workload of compressed image data transfer by CPU
• Receive FIFO of 12 cells
• PHY device I/F: UTOPIA Level-1 interface (octet/cell level handshake)
• JTAG boundary scan test functions
• 0.35-µm CMOS process, +5/+3.3-V power supply
- Bus interface +5 V : +5/+3.3-V power supply
- Bus interface +3.3 V : +3.3-V single power supply
