Skyworks Solutions Inc. 534EB000566DG

Overview

534EB000566DG from Skyworks Solutions is a quad-output, factory-programmed crystal oscillator (XO) with DSPLL® clock synthesis, delivering four selectable output frequencies between 10 MHz and 945 MHz. It operates at 2.5 V supply, supports LVPECL output format, and features ±20 ppm total frequency stability over –40 to +85 °C. Used in high-speed networking equipment for FPGA clocking and SERDES timing recovery.

For engineers reviewing the 534EB000566DG datasheet, 534EB000566DG pinout, 534EB000566DG application, or 534EB000566DG equivalent, key selection criteria include its 0.26 ps RMS phase jitter (50 kHz–80 MHz), tristate-enabled output control via OE pin, FS[1:0]-based frequency switching, and industry-standard 5 × 7 mm 8-pin package compatibility.

Technical Context

The 534EB000566DG implements third-generation DSPLL® architecture to synthesize low-jitter clocks from a single internal fixed-frequency crystal, eliminating need for multiple crystals per frequency. Its digital PLL enables precise frequency selection across four user-configured outputs without external components.

Frequency selection is controlled by two logic-level inputs (FS[1], FS[0]), each with internal 17 kΩ pull-up resistors to VDD, enabling hardware-selectable output switching within 20 ms. Output enable (OE) provides active-high tristate control, reducing supply current to 60–75 mA in disabled mode.

FAQ

What output frequencies are programmed into the 534EB000566DG?

The 534EB000566DG is a factory-programmed quad XO with four specific frequencies determined by the six-digit code "000566". 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 specified in the device's configuration record and can be retrieved via Skyworks' ClockBuilder Pro tool using the full part number 534EB000566DG.

Does the 534EB000566DG require external configuration or programming after soldering?

No, the 534EB000566DG is fully factory-configured and does not require post-soldering programming. All parameters-including output frequencies, supply voltage (2.5 V), LVPECL output format, temperature stability (±20 ppm), and OE polarity-are permanently programmed into nonvolatile memory prior to shipment. The device operates immediately upon power-up with no I²C, SPI, or other interface needed.

Can the 534EB000566DG operate with a 3.3 V supply?

No, the 534EB000566DG is configured for 2.5 V operation only, as indicated by the "E" in the second option code position of the part number. Applying 3.3 V exceeds the absolute maximum rating for the 2.5 V option (VDD ≤ 2.75 V) and risks permanent damage. For 3.3 V operation, a variant such as 534AB000xxxDG must be selected.

What is the function of the NC pin (Pin 1) on the 534EB000566DG?

Pin 1 of the 534EB000566DG is designated No Connection (NC) for both LVPECL and CMOS configurations. It is not bonded internally and must remain unconnected-neither tied to VDD, GND, nor any signal. PCB layout should avoid routing traces or placing vias under this pad to prevent unintended coupling or mechanical stress.

How does the 534EB000566DG achieve ±20 ppm total frequency stability?

The 534EB000566DG achieves ±20 ppm total stability through a combination of ±20 ppm temperature coefficient (over –40 to +85 °C) and ±10 ppm aging over 20 years, as specified in Table 2 of the datasheet. This value excludes initial calibration error (±1.5 ppm), resulting in a guaranteed worst-case deviation of ±20 ppm across lifetime and temperature, verified per MIL-STD-883 environmental testing.
