Skyworks Solutions Inc. 533AA000663DGR

Overview

533AA000663DGR from Skyworks Solutions is a dual-frequency, factory-programmed crystal oscillator (XO) with DSPLL® synthesis, delivering two user-selectable output frequencies from 10 MHz to 945 MHz (or select frequencies up to 1.4 GHz), ±7 ppm temperature stability, 3.3 V supply, and LVPECL output in a 5 × 7 mm 6-pin package. It serves as a low-jitter clock source for FPGA/ASIC timing and high-speed serial interfaces.

For engineers reviewing the 533AA000663DGR datasheet, 533AA000663DGR pinout, 533AA000663DGR application, or 533AA000663DGR equivalent, this device supports frequency switching via FS pin, output enable via OE pin, and operates across –40 °C to +85 °C with <0.40 ps RMS phase jitter (12 kHz–20 MHz, >500 MHz).

Technical Context

The 533AA000663DGR implements third-generation DSPLL® circuitry using a fixed internal crystal reference to synthesize two precise output frequencies without external components. Its architecture enables superior supply noise rejection and eliminates crystal variability across frequency variants.

Frequency selection is controlled by the FS pin (pin 2), while OE (pin 1) enables or tristates both outputs. The device supports LVPECL output with differential swing of 1.1–1.9 V_PP, mid-level at V_DD – 1.42 V, and achieves 2 ps RMS period jitter - critical for SONET/SDH and CDR applications requiring deterministic timing.

FAQ

What output frequencies are programmed in the 533AA000663DGR?

The 533AA000663DGR is a factory-programmed dual-frequency XO. Per Skyworks' part numbering convention, the six-digit code "000663" corresponds to two specific frequencies within the 10–945 MHz band. Exact values are defined at order time and documented in the device's configuration record; typical examples include 125 MHz / 156.25 MHz or 622.08 MHz / 669.326 MHz depending on the frequency pair selected during programming.

Does the 533AA000663DGR support CMOS output?

No, the 533AA000663DGR does not support CMOS output. Its part number suffix "A" indicates LVPECL output format. CMOS is only available in variants with option codes C, G, J, P, T, or V per the ordering guide; those parts also limit maximum frequency to 160 MHz, unlike the 533AA000663DGR's 945 MHz capability.

How is frequency selection implemented on the 533AA000663DGR?

Frequency selection on the 533AA000663DGR is performed using the FS (Frequency Select) pin (pin 2). When FS = 0, the device outputs its lower factory-programmed frequency (f₀); when FS = 1, it outputs the higher frequency (f₁). The pin includes an internal 17 kΩ pull-up resistor to V_DD, so a direct connection to GND selects f₀, while leaving it open or driving high selects f₁.

What is the meaning of "DGR" in the 533AA000663DGR part number?

In the 533AA000663DGR part number, "D" denotes the output enable polarity (high-active), "G" specifies the operating temperature range (–40 °C to +85 °C), and "R" indicates tape-and-reel packaging. This matches Skyworks' official ordering convention in Section 3 of the Si533 datasheet Rev. 1.4.

Can the 533AA000663DGR be used in place of a traditional single-output XO?

Yes, the 533AA000663DGR can replace a single-output XO by fixing the FS pin to a static logic level (e.g., tied to V_DD or GND) to select one of its two programmed frequencies. Its LVPECL output, ±7 ppm stability, and 0.25 ps jitter meet or exceed requirements for most high-performance single-frequency applications - with added flexibility for future dual-frequency upgrades.
