DC1141A-E

DC1141A-E demonstration circuit features the LTC6930-8.19 very low power precision silicon oscillator with a frequency error less than 0.09% at 25°C. For each oscillator, the user can select one of 8 frequencies between 32.768kHz and 8.192MHz. Based on fixed host oscillator frequency internal frequency dividers between 1 and 128 provide 8 different frequencies. The LTC6930 requires no external components other than power supply bypass capacitors and operates with a single 1.7V to 5.5V supply. A DC1141A PCB assembly consists of a 2inch (50.8mm) X 2inch (50.8mm) buffer board with a BNC output and a DIP-8 oscillator board mounted on an 8-pin socket. The DIP-8 oscillator board can be removed from the buffer board and used for prototyping. The three digitally controlled inputs of an LTC6930-8.19 (DIVA, DIVB and DIVC) can be set on a DC1141A-E with three jumblers or set externally by connecting wires to the on-board turrets.

• 8.192MHz highest frequency (DIVC, DIVB, DIVA is 000)
