RF input2 µPC1687G/GV PIN EXPLANATION Pin No. 1 2 Symbol OSC base (bypass) Function and Explanation Internal oscillator consists in balance amplifier. 2 pin and 3 pin should be externally equiped with tank resonater circuit in order to oscillate with feedback loop. OSC base (feedback) 1 pin should be grounded through coupling capacitor to 5 pF. 3 OSC collector (coupling) 3 pin is defined as open collector. This pin should be coupled through resistor or chock coil in order to adjust Q and be supplied voltage. In case of abnormal oscillation, adjust its Q lower to stabilize the operation. 4 VCC Supply voltage pin for the IC. 5 IF output IF output pin. IF amplifier is designed as singleend push-pull amplifier. This pin is assigned for the emitter follower output with 50 Ω constant resistive impedance in wide band. 6 GND GND pin for the IC. 7 RF input 1 (bypass) 7 pin and 8 pin are inputs for mixer designed as double balanced type. Either pin can be assigned for input and another for ground. 8 Equivalent Circuit 3 1 2 VCC to OSC buffer amp.

Data Sheet P11101EJ4V0DS00 µPC1687G/GV NOTE ON CORRECT USE (1) Observe precautions for handling because of electro-static sensitive devices. (2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired oscillation). (3) Keep the track length of the ground pins as short as possible. (4) Connect a bypass capacitor (example: 1 000 pF) to the VCC pin. RECOMMENDED SOLDERING CONDITIONS This product should be soldered under the following recommended conditions.

To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. • NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. M7 98. 8
