1. A 0.01uF and a 0.1uF capacitor should be located as close to the supply as possible (to ground) is recommended.
2. Output is DC coupled

VCXO Functional Description
VCXO Feature:
The VTM3 can be ordered with a VCXO function for applications where it will be used in a
PLL, or the output frequency needs fine tune adjustments. This is a high impedance input, 0.5 Mohm, and
can be driven with an op-amp or terminated with adjustable resistors etc.
Pin 1 should not be left
floating
on the VCXO optional devices.
“No Adjust” Feature:
In applications where the VTM3 will not be used in a PLL, or the output frequency
does not fine tune adjustments, the best device to use would be a VTM3-x0xx. By using the “no adjust”
option, the circuit is simplified as Vc does not need to adjusted or set to a predetermined voltage and
pin
1 should be grounded
(pin 1 can be left open but should not be set to a voltage such as the supply).

Pin 2,5,6,7,8 are used to program and adjust the TCXO during manufacturing and should be left open; do
not terminate these to the supply voltage and are a “make no connection” pad.

丰田汽车召回之中美比较
在路上听说,丰田汽车全球召回中,国内的丰田车仅仅是在4s店中维修,究其缘由: 美国有一法律,若生产厂商有质量问题,如果不召回,一辆车会罚起2亿的罚金,这样丰田不得不召回。 但国内并无 ......
