512 - 1500 MHz Low-Power Divide-by-4 Prescaler | Peregrine Semiconductor
部品番号: 512 ✗ 生産終了512 概要
A prescaler is a frequency divider used to reduce a high-frequency signal by a fixed integer ratio. In the broader electronics hierarchy, a prescaler is a timing and frequency-control circuit within logic ICs and clock-generation systems. It is commonly associated with synthesizers, phase-locked loops, RF transceivers, test instruments, and communication equipment where frequency division helps establish lower-rate timing or reference signals.
The key identified features of the 512 are its 1500 MHz input or operating frequency, divide-by-4 frequency division, low-power operation, and UltraCMOS process technology. The divide-by-4 architecture is useful when a design requires a quarter-frequency output while retaining a high-frequency source signal. Its low-power characteristics are important in systems where the prescaler must operate continuously without adding excessive thermal load or consuming substantial supply current.
The part is associated with an 8-pin datasheet package, but the retrieved technical listing does not expose the complete electrical ratings, control logic, supply voltage, output waveform, insertion loss, or temperature range. Engineers should use the manufacturer’s original 512 datasheet and package drawing when assigning pins or designing the surrounding RF circuit. The 8-pin notation identifies the documentation package format but does not establish whether the device uses a leaded, surface-mount, or exposed-pad construction.
Typical applications include RF frequency synthesizers, phase-locked loop reference dividers, microwave signal-chain subharmonics, communications test equipment, and frequency-generation modules. The 1500 MHz operating point makes the device most relevant to designs operating at or below that frequency, with attention to the divider’s input range, output characteristics, and required bias conditions.
A critical design consideration is confirming the device’s control or self-bias configuration before final PCB layout. Because the available technical record does not specify the enable, supply, ground, and signal pin functions, do not infer a pinout from the package count alone. Preserve the manufacturer’s recommended grounding and impedance-controlled connection geometry, and validate startup, output amplitude, and harmonic content in the intended system.
This product page consolidates the identified 512 prescaler characteristics, source links, design cautions, and application context. It is intended to help engineers identify the correct component quickly while keeping unresolved electrical and pin-level details explicitly traceable to the manufacturer datasheet.

主な用途

RF Frequency Synthesizer
The 512 fits a high-frequency synthesizer reference-divider position when the design requires a divide-by-4 operation around the device’s identified 1500 MHz operating frequency. It can generate a quarter-frequency signal from the synthesizer’s high-frequency source, which is useful when the phase-locked loop needs a lower reference while retaining high-frequency prescaling. The design should follow the manufacturer’s recommended biasing and RF connection arrangement. Before implementation, confirm input drive level, output amplitude, control configuration, and permissible operating range, because these electrical details are not specified in the available listing.
Phase-Locked Loop Reference Divider
As a prescaler, the 512 can divide a high-frequency loop signal by four to create a lower-rate signal for phase comparison or programmable divider stages. Its identified 1500 MHz low-power UltraCMOS construction makes it relevant to compact RF and microwave phase-locked loops where power consumption matters. The principal engineering benefit is the fixed divide-by-4 ratio, which reduces the frequency presented to subsequent loop circuitry. Validate phase noise, output drive, startup behavior, and power-supply requirements against the original manufacturer datasheet before using the device in a production PLL.
Microwave Signal-Chain Subharmonic
The 512 can provide a divide-by-4 subharmonic when a microwave subsystem needs a lower-frequency component derived from a 1500 MHz-class source. This application may support mixer drive generation, local-oscillator distribution, or frequency conversion architectures where direct division is simpler than generating an additional low-frequency source. Because the available record does not specify insertion loss, output level, input sensitivity, or harmonic rejection, engineers should characterize the complete cascade with the manufacturer’s recommended circuit and verify that the divided signal meets the receiving stage’s amplitude and impedance requirements.
Communications Test Equipment
The 512 is applicable to communications test equipment that requires a compact divider to derive a predictable subharmonic from a high-frequency reference. A divide-by-4 path can support excitation, calibration, or signal-generation subsystems operating around the identified 1500 MHz frequency while limiting power consumption. The fixed ratio makes system timing easier to reason about than with a programmable divider. For laboratory and production-test equipment, confirm output level, harmonic content, temperature stability, and bias requirements from the manufacturer documentation before defining the instrument’s measurement limits.
RF Signal Generator
A 1500 MHz low-power divide-by-4 prescaler can serve as an internal reference-division element in a compact RF signal generator. Dividing the generator’s high-frequency oscillator output by four can create a lower-rate signal suitable for downstream modulation, calibration, or measurement paths. The 512’s low-power identity is advantageous in portable or multi-channel instrumentation where each divider contributes to total thermal load. Use controlled-impedance routing and verify startup and output stability across the intended frequency range, since the available listing does not establish those performance parameters.
Microwave Communication Module
The 512 is suitable for consideration in a microwave communication module that derives a divided clock or reference from a high-frequency carrier source. Its divide-by-4 operation can reduce the rate entering later digital or analog blocks, while the identified 1500 MHz class supports RF systems operating around that frequency. The design must account for gain, phase stability, harmonics, and supply conditions rather than assuming ideal digital behavior. A complete implementation should follow the manufacturer’s application guidance and use controlled impedance to prevent the divider from degrading the source signal.

設計ノート
Use the manufacturer’s package drawing and recommended application circuit before assigning PCB pads. The available listing identifies an 8-pin package but does not provide terminal names, pin order, dimensions, or exposed-pad information. Treat the footprint as unconfirmed until those details are checked. Keep the RF input path short, provide a continuous ground reference, and route the divided output as a controlled-impedance trace to limit reflections and preserve divider performance.
Confirm the 512’s required supply voltage, bias method, control state, and current consumption from the original manufacturer datasheet. Do not infer power-pin polarity or operating state from the generic part number. The device is identified as low-power, but its actual dissipation depends on supply voltage, input drive, output loading, and operating frequency. Validate the bias network at minimum and maximum expected input conditions before releasing a production layout.
Avoid confusing the 512 prescaler with unrelated 512-marked EEPROM, flash memory, regulator, or storage products. The functional distinction is the 1500 MHz low-power UltraCMOS divide-by-4 operation. For a replacement, match the exact package, pinout, frequency, divide ratio, bias method, output level, and RF performance. A matching numeric MPN or a similar package description alone is not sufficient evidence of drop-in compatibility.
Characterize the divided output for amplitude, harmonics, phase behavior, and startup across the intended operating band. These specifications are not available in the current listing and must be obtained from the manufacturer. Use controlled impedance and minimize discontinuities on the input and output paths. If the 512 drives a divider chain or mixer, include sufficient isolation to prevent the driven stage from loading the prescaler output.
