Skyworks Solutions Inc. 534FC002389DG

Overview

534FC002389DG from Skyworks Solutions is a quad-output, factory-programmed crystal oscillator (XO) delivering four selectable frequencies between 10 MHz and 945 MHz using DSPLL® synthesis. It features LVDS output, 3.3 V supply, ±7 ppm temperature stability, and operates across –40 °C to +85 °C for use in FPGA clocking, SD/HD video timing, and network switch synchronization.

For engineers reviewing the 534FC002389DG datasheet, 534FC002389DG pinout, 534FC002389DG application, or 534FC002389DG equivalent, this device supports frequency selection via FS[1:0], output enable control, low-jitter performance (0.36 ps RMS phase jitter at 125–500 MHz), and industry-standard 5 × 7 mm 8-pin package compatibility.

Technical Context

The 534FC002389DG implements Skyworks' third-generation DSPLL® architecture with a fixed internal crystal reference, enabling any-rate frequency synthesis without external VCXO tuning. Its digital PLL provides high supply noise rejection and eliminates crystal aging sensitivity associated with traditional XOs.

Frequency selection is controlled by two logic inputs (FS[1], FS[0]), each with internal 17 kΩ pull-up resistors to VDD, supporting four discrete output frequencies. Output enable (OE) places CLK+/CLK– into high-impedance state with 60–75 mA tristate current draw.

Key Specifications

Pinout & Package

534FC002389DG is housed in an industry-standard, RoHS-compliant 5 × 7 mm 8-pin surface-mount package with exposed pad (no thermal pad connection specified). Pin 1 is marked by a dot; pins are arranged in two rows of four (1–4 top row left-to-right, 5–8 bottom row left-to-right).

FAQ

What output format and supply voltage does the 534FC002389DG use?

The 534FC002389DG uses LVDS differential output and is configured for 3.3 V operation (VDD = 2.97–3.63 V). Its CLK+/CLK– outputs require 100 Ω differential termination and deliver 0.5–0.9 VPP swing with 45–55% duty cycle symmetry. This configuration is fixed at factory shipment and cannot be altered in-system.

How many output frequencies does the 534FC002389DG support, and how are they selected?

The 534FC002389DG supports exactly four factory-programmed output frequencies, selected via the two-pin FS[1:0] interface. Each combination (00, 01, 10, 11) routes a distinct frequency to CLK+/CLK–. Selection changes take ≤20 ms to settle, and both pins include internal 17 kΩ pull-up resistors to VDD.

What is the phase jitter performance of the 534FC002389DG at 156.25 MHz?

At 156.25 MHz output, the 534FC002389DG delivers 0.36 ps RMS phase jitter (typical) over the 12 kHz–20 MHz offset range, meeting OC-48 SONET requirements. This value is measured under LVDS output conditions with proper termination and applies directly to the factory-configured frequency set including 156.25 MHz.

Does the 534FC002389DG require an external crystal or loop filter?

No, the 534FC002389DG contains an internal fixed-frequency crystal and fully integrated DSPLL® circuitry. It requires no external crystal, VCXO, loop filter components, or configuration EEPROM. All timing parameters-including frequency, stability, and output format-are programmed during manufacturing and immutable in the field.

What is the operating temperature range and aging specification for the 534FC002389DG?

The 534FC002389DG operates from –40 °C to +85 °C and exhibits ±7 ppm temperature-induced frequency deviation. Its aging specification is ±3 ppm over the first year and ±10 ppm over 20 years-guaranteed by Skyworks' internal crystal stabilization process and validated per MIL-STD-883 methods.
