NJW1508V-TE1

Overview

The NJW1508V-TE1 is a PLL frequency synthesizer designed for TV and VCR tuning systems. It integrates a prescaler operating up to 1.0 GHz and an I2C bus interface. The device features a buffer amplifier for external reference signals, unlike the NJW1504 which includes an internal oscillator. Operating voltage ranges from 4.5V to 5.5V with a typical current consumption of 15mA. It provides a maximum tuning voltage output of 34V and supports programmable division ratios between 256 and 32767 via digital control.

Feature Summary

Integrated prescaler supporting input frequencies up to 1 GHz
I2C bus controlled for programmable divider and band switching
Buffer amplifier for external crystal reference signal
Maximum tuning voltage output of 34V

Applications

TV tuner systems
VCR tuning circuits
Frequency synthesis applications requiring I2C control

Procurement Notes

Verify the TE1 suffix indicates the specific tape and reel packaging configuration. Confirm the component matches the 16-LSSOP package dimensions and pinout as specified in the datasheet. Ensure the ordering information aligns with the manufacturer's standard supply formats.

Selection Notes

Select the NJW1508V over the NJW1504 when an external reference clock source is available, as the NJW1508 lacks an internal oscillator. Ensure the application requires a 5V supply and utilizes the I2C protocol for frequency programming. Verify that the 1 GHz maximum input frequency meets the system requirements.

Part Context

This component belongs to the NJW1504/1508 series of PLL synthesizers manufactured by Nisshinbo Micro Devices Inc. (formerly New Japan Radio). These devices are specialized for analog video equipment tuning applications, providing stable frequency generation through digital control interfaces.

Replacement Considerations

The NJW1504V is a direct functional substitute if the design accommodates an internal crystal oscillator rather than an external reference. Both share identical pinouts and electrical characteristics except for the reference input stage.
