The XHFC-2SU is a single-chip ISDN transceiver for two ISDN S/T or UpN/Up0 Basic Rate Interfaces with integrated HDLC controllers for all kinds of BRI equipment. The XHFC-2SU has two Universal ISDN Ports which can be configurated either in S/T mode or in Up mode, numbered 0 . . 1.
The integrated microprocessor bus interface of the XHFC-2SU can be configured to 8 bit parallel microprocessor interface or serial processor interface (SPI). A PCM128 / PCM64 / PCM30 interface for CODEC or inter-chip connection is also integrated. The deep FIFOs of the XHFC-2SU are realized with an internal SRAM.
|Bus interfaces||SPI, 8 bit parallel|
|CODEC or inter-chip connection||PCM128 / PCM64 / PCM30|
