The XHFC-1SU is a single-chip ISDN transceiver for one ISDN S/T or UpN/Up0 Basic Rate Interface with integrated HDLC controller for all kinds of BRI equipment.
The integrated microprocessor bus interface of the XHFC-1SU 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-1SU are realized with an internal SRAM.
|Bus interfaces||SPI, 8 bit parallel|
|CODEC or inter-chip connection||PCM128 / PCM64 / PCM30|
