TCS2315 GPRS手机解决方案

                  manufacturing cycle time are improved with built-in
                  calibration, drift effects are reduced and auto-compensation
                  for process and temperature variances is enabled. All of these
                  advantages add to the cost savings by reducing the size of the
                  underlying platform and enabling handsets in sleeker, more
                  compact form factors.
