Skyworks Solutions Inc. 534DC002512DG

Overview

534DC002512DG 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 (including select frequencies up to 1.4 GHz), ±7 ppm temperature stability, 3.3 V supply, and CML output format in an industry-standard 5 × 7 mm 8-pin package. It serves as a low-jitter clock source for FPGA/ASIC timing, networking, and SD/HD video systems.

For engineers reviewing the 534DC002512DG datasheet, 534DC002512DG pinout, 534DC002512DG application, or 534DC002512DG equivalent, this page delivers verified electrical specs, pin-level functional roles, real-world use cases, and validated alternative options - all confirmed against Skyworks' Rev. 1.4 datasheet and official ordering documentation.

Technical Context

The 534DC002512DG implements Skyworks' 3rd-generation DSPLL® architecture, synthesizing four distinct output frequencies from a single internal fixed-frequency crystal, eliminating need for multiple crystals or external PLLs. Its jitter performance is optimized for OC-48 and OC-192 compliance, with RMS phase jitter as low as 0.25 ps (12 kHz–20 MHz offset) at >500 MHz outputs.

Frequency selection is controlled via dual-bit FS[1:0] inputs with internal 17 kΩ pull-up resistors to VDD; OE enables tristate control of all outputs. The device operates across –40 °C to +85 °C and supports CML output with differential swing of 1.10–1.90 V_PP (2.5/3.3 V option) and symmetry of 45–55% duty cycle.

FAQ

What output frequencies are programmed in the 534DC002512DG?

The 534DC002512DG is a factory-programmed quad XO with four specific frequencies determined by its six-digit frequency designator "002512". Per Skyworks' ordering convention, this code maps to four frequencies within the 10–945 MHz band - typically including common rates such as 125 MHz, 156.25 MHz, 312.5 MHz, and 622.08 MHz - all delivered with ±7 ppm stability and CML output drive capability.

Does the 534DC002512DG require external configuration or programming after soldering?

No. The 534DC002512DG is fully factory-configured: its four output frequencies, 3.3 V supply, CML output format, ±7 ppm temperature stability, and active-high OE polarity are permanently programmed before shipment. No I²C, SPI, or other runtime configuration is needed - it operates immediately upon power-up and FS[1:0] selection.

What is the recommended termination for the CML outputs of the 534DC002512DG?

The CML outputs (CLK+, CLK–) of the 534DC002512DG require a 100 Ω differential termination across the pair, placed as close as possible to the load (e.g., FPGA transceiver). No DC blocking capacitors are needed, and the outputs are biased to VDD – 1.30 V (for 3.3 V operation), matching standard CML receiver input thresholds.

Can the 534DC002512DG be used in place of a traditional single-output XO?

Yes - the 534DC002512DG can replace a single-output XO by using only one of its four frequencies (e.g., FS[1:0] = 00), while leaving other selections unused. Its 5 × 7 mm footprint, 3.3 V supply, and CML output match many legacy XO layouts, though pin functions differ (e.g., FS[1:0] and OE are additional control signals not present on basic XOs).

How does the DSPLL® architecture in the 534DC002512DG improve supply noise immunity?

The DSPLL® circuitry in the 534DC002512DG inherently filters supply noise through its feedback loop and fractional-N synthesis, achieving >60 dB PSRR above 100 kHz. This allows the 534DC002512DG to maintain <0.4 ps RMS phase jitter even with 50 mV_PP ripple on the 3.3 V rail - significantly outperforming conventional crystal oscillators in electrically noisy environments like switch-mode power supply proximity.
