Published:2011/4/1 20:26:00 Author:may | Keyword: 18V, observation
When ±18V battery pack discharge and drop to preconcerted low voltage, Zener diode 1N476 lose control function, Q1 become forward bias, LED is shine. At this time we need to replace the batteries or recharge to them. When battery voltage is normal, Zener diode is in reversal of biasing state, Q1 is cut-off, LED fails to shine, it only consumes current less than 1mA.

The diagram is drive circuit which is support to 1024 bit CCPD. It can used for drive of 1024 bit CCPD if change 64 frequency division of LS393 to 128 frequency division. The frequency of quartz crystal unit J1 can change according to actual need at the range of 0.5~10MHz. Two Vs of CCPD is signal output end. Jr is reset pulse exit side. JT is line synchronizing pulse side.
