?11 cxd2400r external synchronization 1) external/internal sync selection external or internal synchronization is selected automatically by a combination of 3 pins (vr/sync, hpll and esync) to which the sync signal is input externally. the table below shows the input pattern combinations. note) operation is possible even if the vd cycle of the vd input in the vd/hd sync mode is longer than normal. the ext pin is the external/internal sync identification signal output pin. this output signal can be used as the signal to select lc oscillation for expanding the lock range for external synchronization or the oscillator for improving the oscillation accuracy for internal synchronization. 2) modes for external synchronization * the characteristics of ccd image sensors are guaranteed for field accumulation operation. 3) reset operation sync synchronization the vr1 signal component is extracted from the sync signal supplied externally and, for eia, v reset is performed so that the vdo pulse falls at the count of 259h (262.5 ?3.5h) from the fall of the vr1 pulse. for ccir, it is reset in such a way that the vdo pulse falls at the count of 309h (312.5 ?3.5h). for these reasons, it is a prerequisite that the sync signal input comply with the eia or ccir standard. vd/hd synchronization v reset is performed so that the vdo pulse falls 1h later after detecting the fall of the vd (vdr) pulse supplied externally. therefore, this enables v reset operation regardless of the field line number. the phase difference between the vdr pulse and hdo pulse which is locked horizontally at pll circuit identifies whether the field is odd or even. (vdr must have a pulse width of 2h or more.) input pattern ext pin output sync state vr/sync pin: sync signal hpll pin: open esync pin: open high external sync vr/sync pin: vd signal hpll pin: hd signal esync pin: v dd (power supply) high external sync vr/sync pin: open hpll pin: open esync pin: open low internal sync sync synchronization interlace non-interlace field accumulation o (cannot be accomplished since interlace operation is the prior condition.) o o frame accumulation * o (cannot be accomplished since interlace operation is the prior condition.) o (not practically applicable since the sensitivity is halved.) interlace non-interlace vd/hd synchronization
