Skyworks Solutions Inc. 534FB002370DG

Overview

534FB002370DG from Skyworks Solutions is a quad-output, factory-programmed crystal oscillator (XO) with DSPLL® frequency synthesis, delivering four selectable LVDS output frequencies between 10 MHz and 945 MHz. It operates from a 2.5 V supply, offers ±20 ppm total frequency stability over –40 to +85 °C, and achieves 0.34 ps RMS phase jitter (50 kHz–80 MHz, OC-192) for high-speed serial link timing in networking equipment.

For engineers reviewing the 534FB002370DG datasheet, 534FB002370DG pinout, 534FB002370DG application, or 534FB002370DG equivalent, this device serves as a low-jitter, multi-frequency clock source requiring precise frequency selection via FS[1:0], output enable control, and stable LVDS signaling in FPGA-based infrastructure platforms.

Technical Context

The 534FB002370DG implements Skyworks' third-generation DSPLL® architecture, synthesizing four distinct output frequencies from a single internal fixed-frequency crystal-eliminating need for multiple crystals while maintaining high reliability and low aging (±3 ppm first-year drift). Its all-digital PLL enables superior supply noise rejection and fast frequency switching (≤20 ms settling after FS[1:0] change).

It supports LVDS differential outputs with 0.7 VPP typical swing, 45–55% duty cycle symmetry, and operates across –40 to +85 °C ambient with 2.5 V supply. The device integrates internal 17 kΩ pull-up resistors on OE and FS[1:0] pins, simplifying system-level interface design without external biasing components.

Key Specifications

Pinout & Package

534FB002370DG is housed in an industry-standard 5 × 7 mm, 8-pin surface-mount package with exposed pad (not electrically connected). Pin 1 is marked by a dot; the device uses a top-view layout with GND at Pin 3, VDD at Pin 6, and dual-purpose FS[1]/FS[0] pins enabling four discrete output frequencies.

FAQ

What output frequencies are programmed into the 534FB002370DG?

The 534FB002370DG is factory-programmed with four specific LVDS output frequencies determined by its six-digit configuration code '002370'. Per Skyworks' ordering convention, this code maps to four frequencies within the 10–945 MHz range, selected during manufacturing and documented in the device's configuration report. The exact values are not publicly decoded in the datasheet but are fixed and verified at shipment; users select them via Skyworks' ClockBuilder Pro tool prior to order placement.

Does the 534FB002370DG support CMOS output mode?

No, the 534FB002370DG does not support CMOS output. Its ordering code 'F' indicates 2.5 V supply with LVDS output format (per Table on page 7 of the datasheet). CMOS is only available for part numbers with option codes 'G', 'J', 'T', or 'V'; the 'F' suffix explicitly denotes LVDS. Attempting to drive CMOS loads will violate output voltage and current specifications and may cause timing errors or device stress.

What is the function of the NC pin (Pin 1) on the 534FB002370DG?

Pin 1 of the 534FB002370DG is designated NC (No Connection) and is internally unconnected. It must not be soldered to any net on the PCB. While it may be left floating, best practice is to tie it to GND for mechanical reinforcement and improved thermal dissipation-provided no electrical connection is made to active circuitry. This pin has no functional role in power, signal, or control paths.

How does the 534FB002370DG achieve ±20 ppm total frequency stability?

The 534FB002370DG achieves ±20 ppm total stability by combining ±20 ppm temperature stability (over –40 to +85 °C), ±3 ppm first-year aging, and ±1.5 ppm initial accuracy at +25 °C. These values are guaranteed at time of shipment and reflect worst-case cumulative deviation across all specified conditions-enabling reliable timing in telecom and industrial environments without recalibration.

Can the 534FB002370DG be used in place of a traditional single-output XO?

Yes, the 534FB002370DG can replace a single-output XO by configuring only one of its four frequencies (e.g., setting FS[1:0] = 00 permanently) and leaving other selections unused. Its LVDS output, 2.5 V supply, and 5×7 mm footprint maintain compatibility with standard XO layouts, while offering headroom for future multi-clock upgrades without board redesign.
