Skyworks Solutions Inc. 534AB000428DG

Overview

534AB000428DG from Skyworks Solutions is a quad-output, factory-programmed crystal oscillator (XO) with DSPLL® frequency synthesis, delivering four selectable output frequencies between 10 MHz and 945 MHz (LVPECL/LVDS/CML) or up to 160 MHz (CMOS), ±20 ppm total stability over –40 to +85 °C, 3.3 V supply, and LVDS output format - used in FPGA clock generation, SD/HD video timing, and network switch synchronization.

For engineers reviewing the 534AB000428DG datasheet, 534AB000428DG pinout, 534AB000428DG application, or 534AB000428DG equivalent, this page delivers verified electrical specs, pin-level functional roles, real-world use cases, and validated alternative options for high-reliability timing design in communication and embedded systems.

Technical Context

The 534AB000428DG implements Skyworks' 3rd-generation DSPLL® architecture to synthesize low-jitter clocks from a single internal fixed-frequency crystal, enabling any-rate outputs without custom crystals. It supports frequency selection via dual-bit FS[1:0] control with 20 ms settling time after change.

It features integrated OE (output enable) with 17 kΩ pull-up, operates across –40 to +85 °C, and delivers LVDS differential outputs with 0.5–0.9 VPP swing, 45–55% duty cycle symmetry, and 1.125–1.275 V mid-level - all compliant with industry-standard 5 × 7 mm 8-pin package dimensions.

Key Specifications

Pinout & Package

FAQ

What output frequencies are programmed into the 534AB000428DG?

The 534AB000428DG is factory-programmed with four specific output frequencies determined by its six-digit frequency designator "000428". Per Skyworks' ordering convention, this code corresponds to a defined quad-frequency set within the 10–945 MHz range, delivered as LVDS outputs. Exact values are specified in the device's configuration record and can be retrieved using Skyworks' ClockBuilder Pro software with the part number.

Does the 534AB000428DG require external configuration after soldering?

No, the 534AB000428DG is fully factory-configured before shipment - including output frequencies, LVDS format, 3.3 V supply, ±20 ppm stability, and active-high OE polarity. No I²C, SPI, or programming interface exists; operation begins immediately upon power-up with FS[1:0] selecting among the four preloaded frequencies.

Can the 534AB000428DG operate with a 2.5 V supply?

No, the 534AB000428DG is specifically ordered with a 3.3 V supply option (denoted by "A" in the second option code position). Its absolute maximum VDD rating is 3.8 V, and operation below 2.97 V violates recommended operating conditions - potentially causing startup failure or degraded jitter performance.

What is the function of the NC pin (Pin 1) on the 534AB000428DG?

Pin 1 on the 534AB000428DG is designated NC (No Connection) and has no internal electrical connection. Skyworks specifies it may be left unconnected or tied to GND for mechanical stability - but it must never be driven or used as a signal path, as doing so risks violating the device's thermal and ESD design margins.

How does the 534AB000428DG achieve low phase jitter without an external loop filter?

The 534AB000428DG integrates Skyworks' third-generation DSPLL® core, which embeds the loop filter and VCO within the IC alongside a fixed-frequency crystal resonator. This monolithic architecture eliminates external component sensitivity and provides guaranteed 0.36 ps RMS phase jitter (12 kHz–20 MHz) without requiring user-designed analog filters or tuning.
