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.
