Block Diagram SAB 82525/SAB 82526
The HSCX SAB 82526 comprises one (channel B), the SAB 82525 two completely
independent full-duplex HDLC channels (channel A and channel B), supporting various layer-1
functions by means of internal oscillator, Baud Rate Generator (BRG), Digital Phase Locked
Loop (DPLL), and Time-Slot Assignment (TSA) circuits.
Furthermore, layer-2 functions are performed by an on-chip LAP (Link Access Procedure, e.g.
LAPB or LAPD) controller.
