7. FUNCTIONAL DESCRIPTIONS
7.1 Main Block Functions
The functional block diagram of W66910 is shown in Fig.6.1. The main function blocks are :
Layer 1 function according to ITU-T I.430
Serial Interface Bus (SIB)
B channel switching
GCI bus interface
PCM port (x 2) and internal B channel switching
D channel HDLC controller
B channel HDLC controllers (x 2)
Peripheral control
The layer 1 function includes:
S/T bus transmitter/receiver
Timing recovery using Digital Phase Locked Loop (DPLL) circuit
Layer 1 activation/deactivation, TE mode
D channel access control
Frame alignment
Multi-frame synchronization
Test functions
The serial interface bus performs the multiplexing/demultiplexing of D and 2B channels.
The B channel switching determines the connection between layer 1/GCI, layer 2 and PCM.
The GCI circuit is used to connect a U transceiver (slave mode) or other slave GCI device such as CODEC (master mode).
The PCM port provides two 64 kbps clear channels to connect to PCM codec chips.
The D channel HDLC controller performs the LAPD (Link Access Procedure on the D channel) protocol according to ITU-T
I.441/Q.921 recommendation.
There are two independent B channel HDLC controllers. They can be used to support HDLC-like protocols such as Internet PPP.
Two S/T B channels can also be programmed to 128Kbps mode with one HDLC controller to support IDSL or OCN (in Japan)
application.
In embedded application, a 8-bit microprocessor interface is used to control the chip.
The peripheral control block is used to control other peripheral devices such as CODEC, SLIC, DTMF detector, LEDs.
