GSM Co-Processor for Advanced Features (GOLD-SX)
PMB 2708
General Description
Type
Package
The GOLD-SX is part of a complete chip set which covers all
functions of a mobile radio for the Global System for Mobile
communications, GSM. A mobile terminal which contains this
chip set can meet all performance requirements set down in
the Technical Specifications for GSM, PCN and PCS-1900.
PMB 2708_1-F (GOLD-SXH) P-TQFP-64-1 (SMD)
PMB 2708_2-F (GOLD-SXE) P-TQFP-64-1 (SMD)
– Serial data exchange with Half-Rate Channel Codec
and voiceband unit on GOLD-SP
– Serial data exchange with system simulator interfacing
box (GSM 11.10)
GOLD-SX is used for advanced features. The function of the
GOLD-SX is dependent on its firmware.
The first version of the GOLD-SX performs Half-Rate speech
encoding including Voice Activity Detection (VAD) and
Discontinuous Transmission (DTX), as well as Half-Rate
speech decoding including Discontinuous Reception (DRX,
Comfort Noise).
• Enhanced Full-Rate Codec (GOLD-SXE):
– GSM Enhanced Full-Rate Codec (GSM 6.51, 6.53,
6.54, 6.60)
– Voice activity detection, VAD (GSM 6.82)
– Discontinuous transmission, DTX (GSM 6.81)
– Comfort noise generation, DRX (GSM 6.62)
– Serial data exchange with Enhanced Full-Rate Channel
Codec and voiceband unit on GOLD-SP
– Serial data exchange with system simulator interfacing
box (GSM 11.10)
The second version performs Enhanced Full-Rate speech
coding including all the DTX functions as in Half-Rate speech
coding.
Features
