The HFC-E1 is a HDLC B- and D-channel controller with integrated E1 (S2M) interface and can be used for ISDN primary rate lines with 30 B- and two D-channels for a bandwidth of 2.048 Mbit/s. All channels are served fully duplex by deep FIFOs.
The integrated universal bus interface of HFC-E1 can be configured to PCI, ISA Plug and Play, PCMCIA, parallel microprocessor interface or SPI. A PCM128 / PCM64 / PCM30 interface for CODEC or inter chip connection is also integrated.
|Bus interfaces||PCI, PCMCIA, SPI, 8 bit parallel|
|CODEC or inter-chip connection||PCM128 / PCM64 / PCM30, H.100|
|Technology features||CMOS 3.3 V technology, 5 V tolerant on nearly all inputs|
