ISDN BRI controller with S/T ref. pt. analog D/R
YTD436 is a high-performance communication LSI for the ISDN BRI user-network
interface function (digital four-wire time-division full-duplex operation), supporting D
channel layer 1 and layer 2 functions in one 100-pin SQFP chip.
YTD436 supports layer 1 (physical layer) control function conforming to ITU-T
Recommendation I.430 and fully supports layer 2 (LAPD protocol) function conforming to
ITU-T Recommendations Q.920 and Q.921. ETSI (European Telecommunication Standards
Institute) and North American standard operating modes are also supported.
In addition, YTD436 includes layer 3 processor interface function which operate in DMA
transfer mode or I/O transfer mode. This gives a great advantage for mounting and
functional designing of both “active” (CPU on board) terminal equipment and “passive” (no
CPU on board) PC cards.
The layer 1 function has a built-in S/T reference point analog driver/receiver to support the
S/T reference point interface. In order to support the U interface, YTD436 also has a I.430
TTL interface (no built-in analog driver/receiver) suitable for connecting to an NT1 chip or
a DSU module.

... YTD436 is the most-suited LSI for terminal equipment such as ISDN telephones and video telephones and for PHS base stations. YTD436 contains layer 1 and layer 2 functions, analog driver/receiver for the S/T reference point, DMA request function for B channel data transfer, and DMA controller for D channel data transfer. Because of this, terminal equipment can be optimally configured by adding few circuits such as the layer 3 control processor ...
