The XHFC-2S4U is the inexpensive choice for ISDN UpN/Up0 equipment. Better prices come from less integrated S/T interfaces since this single-chip ISDN transceiver offers two ISDN S/T and four UpN/Up0 Basic Rate Interfaces with integrated HDLC controllers for all kinds of BRI equipment.
The integrated microprocessor bus interface of the XHFC-2S4U 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-2S4U are realized with an internal SRAM.
