UPB1003GS NEC, UPB1003GS Datasheet - Page 12

• Manufacturer Part Number: UPB1003GS
• Description: REFERENCE FREQUENCY 16.368 MHz/ 2ND IF FREQUENCY 4.092 MHz RF/IF FREQUENCY DOWN-CONVERTER PLL FREQUENCY SYNTHESIZER IC FOR GPS RECEIVER
• Manufacturer: NEC

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 abnormal 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 V
(5) Frequency signal input/output pins must be each coupled with external capacitor for DC cut.
