Skyworks Solutions Inc. 534BB000129DG

Overview

534BB000129DG from Skyworks Solutions is a quad-output, factory-programmed crystal oscillator (XO) delivering four selectable frequencies in the 10–945 MHz range with ±20 ppm temperature stability and LVDS output format. It uses DSPLL® clock synthesis for low jitter (0.34–0.42 ps RMS, 50 kHz–80 MHz), operates from a 3.3 V supply, and is housed in an industry-standard 5 × 7 mm 8-pin surface-mount package. It serves as a high-stability timing source in FPGA clock trees and SD/HD video synchronizers.

For engineers reviewing the 534BB000129DG datasheet, 534BB000129DG pinout, 534BB000129DG application, or 534BB000129DG equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternatives, and supply support for industrial embedded and communications hardware design.

Technical Context

The 534BB000129DG implements Skyworks' 3rd-generation DSPLL® architecture to synthesize four discrete output frequencies from a single internal fixed-frequency crystal, eliminating need for multiple crystals or external PLLs. Its frequency selection is controlled via two logic-level FS[1:0] inputs, enabling dynamic switching between preprogrammed outputs with ≤20 ms settling time.

It integrates internal 17 kΩ pull-up resistors on OE and FS[1:0], supports tristate operation (60–75 mA standby current), and delivers LVDS differential outputs with 0.5–0.9 VPP swing, 45–55% duty cycle symmetry, and 1.125–1.275 V common-mode voltage - all specified across –40 to +85 °C ambient.

FAQ

What output frequencies are programmed into the 534BB000129DG?

The 534BB000129DG is factory-programmed with four specific frequencies within the 10–945 MHz range, determined by its six-digit frequency code "000129". Per Skyworks' ordering convention, this code maps to a defined quad-frequency set - exact values are provided in the device's Certificate of Conformance and can be verified using Skyworks' ClockBuilder Pro software. The frequencies are selected dynamically via the FS[1:0] pins.

Does the 534BB000129DG require external configuration after soldering?

No, the 534BB000129DG is fully factory-configured before shipment. All parameters - including the four output frequencies, LVDS output format, 3.3 V supply, ±20 ppm stability, and active-high OE polarity - are permanently programmed into the device's nonvolatile memory. No external EEPROM, I²C interface, or runtime configuration is needed; it operates immediately upon power-up.

Can the 534BB000129DG be used with a 2.5 V supply?

No, the 534BB000129DG is specifically configured for 3.3 V operation, as indicated by the "B" in its second option code position (534BB000129DG). Attempting to power it from 2.5 V will result in improper functionality or failure to start. For 2.5 V operation, a different part number such as 534EBxxxxxxDG (LVPECL) or 534FBxxxxxxDG (LVDS) must be selected.

What is the maximum load capacitance supported on the LVDS outputs of the 534BB000129DG?

The 534BB000129DG LVDS outputs are specified for 100 Ω differential termination, which corresponds to a 50 Ω load to VDD/2 on each leg in standard LVDS receivers. The datasheet does not define a maximum capacitive load beyond this; however, maintaining PCB trace impedance at 100 Ω differential and minimizing stub length ensures compliance with the 0.5–0.9 VPP swing and 45–55% duty cycle specifications. Excessive capacitance degrades edge rate and jitter.

Is the 534BB000129DG RoHS-compliant and lead-free?

Yes, the 534BB000129DG is Pb-free and RoHS-compliant, as confirmed by its "R" suffix (tape-and-reel packaging) and the "+" mark on the top-side marking per Skyworks' Si534 Mark Specification. It meets JEDEC J-STD-020C MSL1 moisture sensitivity level and is qualified for Pb-free reflow with peak temperature of 260 °C for 20–40 seconds.
