PSB 7280

Integration of these and other features, as well as perfectly matched interfaces with other

ICs allows for the implementation of highly optimized, low cost system solutions e.g. for

Videophones, Data-over-voice and Channel Multiplexing equipment.

For system integration, two serial HDLC/transparent data channels are implemented

which can be serviced by an attached host (or the on-chip DSP). System functions and

communication between the chip and an external controller is supported by a full-duplex

256-byte on-chip mailbox communication memory.

The circuit is offered in a Quad Flat Pack package with 100 pins (P-TQFP-100: size

14 × 14 mm, pitch 0.5 mm, height 1.4 mm).

Note: This Data Sheet gives a thorough description of the functions and hardware that

forms the base of PSB 7280. It includes information (e.g. External Memory

Interface) that is not needed for the PSB 7280 as a “ready to use plug and play”

G.728/G.722/G.711 audio compression device.
