µPD98405
155M ATM INTEGRATED SAR CONTROLLER
DESCRIPTION
The µPD98405 (NEASCOT-S20TM) is a high-performance SAR chip that performs segmentation and reassembly of
ATM cells. It has a PCI bus interface, a SONET/SDH 155-Mbps framer, and a clock recovery circuit and supports an
ABR function in hardware. The µPD98405 conforms to ATM Forum and has the functions of the AAL-5 SAR
sublayer, ATM layer, and TC sublayer.
FEATURES
• Conforms to ATM Forum.
• Host bus interface supporting PCI bus/generic bus.
- PCI interface (5/3.3 V, 32/64 bits, 33 MHz): Conforms to PCI Specification 2.1
- Generic bus interface (5/3.3 V, 32 bits, 33 MHz)
• AAL-5 SAR sublayer, ATM layer, and TC sublayer functions
• Hardware support of AAL-5 processing
• Software support of non-AAL-5 traffic
• SONET STS-3c/SDH STM-1 155-Mbps framer function
• Clock recovery/clock synthesizer function
• Supports up to 32 K virtual channels (VCs)
• Sixteen traffic shapers for VBR for transmission scheduling
• Hardware support of CBR/VBR/ABR/UBR service
• Supports multi-cell burst transfer for transmission and reception
• MIB counter function
• Supports LAN emulation function
• Receive FIFO of 96 cells
• External PHY devices connectable: UTOPIA Level-1 interface
• 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 power supply
• 304-pin plastic QFP
