4.2.4.
FPGA
FPGA (IC103) has the following features.
(1) MPU i/f
MPU i/f module has the address decoder and the data I/O control part, and controls the access between CPU and internal mod-
ule.
ule.
(2) ST-BUS I/F
ST-BUS i/f module controls Serial communications with DNIC, extractes to D channel, C channel(HK bit), and B channel from
the serial data, and this block is distributed these datas to an internal each module.
Moreover, Dch, Cch, and Bch that come from an internal each module are united, and this module outputs it to DNIC by the ST-
BUS format.

(4) HDLC controller
HDLC is the abbreviation of High level Data Line Control, means a protocol for highly reliable data communication.
D channel data from ST-BUS i/f is transmitted to/from CPU through this module.
D channel data from ST-BUS i/f is transmitted to/from CPU through this module.
(5) BBIC PCM I/F
Extracts voice data from ST-BUS digital data and changes format to BBIC PCM format, then provides it to BBIC(IC100).

Power Supply Circuit
6.7V, 4.9V, PA_V3.3V, 3.2V, RF2.5V, RF1.8V, 1.8V and 1.5V are generated in CS.
6.7V is output of DC/DC Convertor. Other power supplies except 3.2V and 1.8V, RF1.8V are made from 6.7V by each regura-
tors.
4.9V is the power supply of DNIC(IC106).
PA_V3.3V and RF2.5V, RF1.8V are the power supply for RF block.
3.2V is the power supply for logic circuit.
1.8V is the power supply for BBIC(IC100).
1.5V is used as the power supply of FPGA(IC103) internal core.

4.2.7.1.
BBIC Clock
10.368MHz crystal oscillator is used.
4.2.7.2.
FPGA Clock
16.384MHz crystal oscillator is used.
4.2.7.3.
DNIC Clock
10.24MHz crystal oscillator is used.
4.2.8.
Reset Circuit
The output signal of reset IC is generated with the detection of 6.7V power supply.
BBIC reset signal(BB_RSTN) is made from reset IC output and the configuration completion status signal of FPGA.
FPGA is reset by the port output from BBIC(IC100).(F_RST)
