Skyworks Solutions Inc. 534AB000503DG

Overview

534AB000503DG 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 (with select options up to 1.4 GHz), ±20 ppm temperature stability, LVDS output format, and 3.3 V supply. It serves as a low-jitter timing source in multi-clock domain systems such as FPGA-based networking equipment.

For engineers reviewing the 534AB000503DG datasheet, 534AB000503DG pinout, 534AB000503DG application, or 534AB000503DG equivalent, key selection criteria include its quad-frequency flexibility, sub-0.4 ps RMS phase jitter (12 kHz–20 MHz), industry-standard 5 × 7 mm 8-pin package, and configurable OE/FS[1:0] control for dynamic clock switching in high-speed serial interfaces.

Technical Context

The 534AB000503DG implements Skyworks' third-generation DSPLL® architecture, synthesizing four precise output frequencies from a single internal fixed-frequency crystal-eliminating need for multiple crystals while maintaining ±20 ppm total stability over –40 °C to +85 °C. Its LVDS outputs deliver 0.5–0.9 V_PP differential swing with 45–55% duty cycle symmetry.

Frequency selection is controlled via two logic-level FS pins with internal 17 kΩ pull-ups to VDD; OE enables/disables all outputs into high-impedance state. Power-up time is ≤10 ms, and frequency reconfiguration after FS[1:0] change settles within 20 ms-critical for adaptive clocking in reconfigurable hardware.

FAQ

What output frequencies are configured in the 534AB000503DG?

The 534AB000503DG is a factory-programmed quad-frequency XO; its four specific output frequencies are encoded in the six-digit "000503" portion of the part number. Per Skyworks' ordering convention, this code corresponds to a defined set of four frequencies within the 10–945 MHz range, selected at time of manufacture. Exact values are documented in the device-specific configuration report provided with shipment, and can be verified using Skyworks' ClockBuilder Pro software.

Does the 534AB000503DG require external configuration or programming after soldering?

No, the 534AB000503DG is fully factory-configured and ready for operation upon power-up. All parameters-including output frequencies, LVDS format, 3.3 V supply, ±20 ppm stability, and OE/FS[1:0] logic polarity-are permanently programmed into nonvolatile memory during manufacturing. No external EEPROM, I²C interface, or firmware load is needed for basic functionality.

Can the 534AB000503DG operate with a 2.5 V or 1.8 V supply?

No-the "A" in the second option code position of 534AB000503DG explicitly denotes a 3.3 V supply option. Devices with 2.5 V or 1.8 V supply require different part numbers (e.g., "E", "F", "G" for 2.5 V; "J", "K", "V", "W" for 1.8 V). Using 534AB000503DG with voltages outside 2.97–3.63 V violates Absolute Maximum Ratings and may cause functional failure or reliability degradation.

What is the meaning of the "B" in the 534AB000503DG part number?

The "B" is the second option code and specifies ±20 ppm temperature stability (and ±31.5 ppm total stability including aging). This matches Table 2's "Temp stability = ±20 ppm" row and defines the device's frequency tolerance across the full –40 °C to +85 °C operating range. It is distinct from "A" (±50 ppm) and "C" (±7 ppm), enabling precise thermal performance targeting for telecom-grade designs.

Is the 534AB000503DG pin-compatible with other Si534 variants like 534AB000108DGR?

Yes-all Si534 devices, including 534AB000503DG and 534AB000108DGR, share identical 8-pin 5 × 7 mm package dimensions, pin assignments, and mechanical footprint per Figure 2 and Table 11. The pinout (GND, OE, VDD, CLK+, CLK−, FS[1], FS[0]) is standardized across the family, enabling drop-in replacement for same-supply-voltage and same-output-format variants without PCB redesign.
