Skyworks Solutions Inc. 533CA000230DGR

Overview

533CA000230DGR from Skyworks Solutions is a dual-frequency, factory-programmed crystal oscillator (XO) with DSPLL® synthesis, delivering two user-selectable output frequencies between 10 MHz and 945 MHz (or select frequencies up to 1.4 GHz), ±7 ppm temperature stability, 3.3 V supply, and LVDS 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 533CA000230DGR datasheet, 533CA000230DGR pinout, 533CA000230DGR application, or 533CA000230DGR equivalent, this device supports frequency switching via FS pin, output enable control via OE pin, and operates across –40 °C to +85 °C with RMS phase jitter as low as 0.36 ps (12 kHz–20 MHz, 125–500 MHz).

Technical Context

The 533CA000230DGR implements third-generation DSPLL® circuitry with a fixed internal crystal reference, enabling precise fractional-N synthesis of two distinct output frequencies without external loop filters or VCO tuning components. Its architecture provides superior supply noise rejection and eliminates crystal aging variability associated with discrete XO designs.

It features dual-frequency selection via a logic-level FS pin, tristate-capable outputs controlled by an OE pin with internal 17 kΩ pull-up, and supports LVDS differential signaling with 100 Ω termination. The device is factory-configured - no field programming required - and complies with MSL1 moisture sensitivity and Pb-free/RoHS requirements.

FAQ

What output frequencies are programmed in the 533CA000230DGR?

The 533CA000230DGR is factory-programmed with two specific frequencies determined by its six-digit configuration code "000230". Per Skyworks' part numbering convention, this code corresponds to two frequencies within the 10–945 MHz band - the exact values are defined at time of order and documented in the device's shipping certificate. The lower frequency is selected when FS = 0; the higher when FS = 1. No field reprogramming is possible.

Does the 533CA000230DGR support LVDS output, and what are the termination requirements?

Yes, the 533CA000230DGR supports LVDS output, as indicated by ordering code 'C' (3.3 V, LVDS, high-enable OE). It requires a 100 Ω differential termination across CLK+ and CLK–, placed as close as possible to the load IC's input. The device specifies 1.125–1.275 V common-mode voltage and 0.5–0.9 VPP differential swing under these conditions - deviations will impact jitter and duty cycle.

How does the 533CA000230DGR achieve ±7 ppm temperature stability?

The 533CA000230DGR achieves ±7 ppm temperature stability through a combination of its internal fixed-frequency crystal resonator and third-generation DSPLL® compensation circuitry. Unlike traditional XOs that rely solely on crystal cut and oven control, the DSPLL continuously corrects for temperature-induced drift using digital feedback - enabling high stability in a small, low-power, non-ovenized package.

Can the 533CA000230DGR operate outside the –40 °C to +85 °C range?

No, the 533CA000230DGR is qualified and specified only for operation across –40 °C to +85 °C ambient temperature. Its electrical parameters - including frequency stability, phase jitter, and supply current - are guaranteed only within this range. Operation beyond these limits may cause parametric shift, increased aging, or functional failure, and is not supported per Skyworks' qualification testing (MIL-STD-883, J-STD-020 MSL1).

Is the 533CA000230DGR pin-compatible with other Si533 variants like 533AB000108DGR?

Yes, all Si533 devices - including 533CA000230DGR and 533AB000108DGR - share identical 6-pin, 5 × 7 mm package dimensions, pinout (GND–FS–VDD–CLK+–CLK––OE), and mechanical footprint. Differences lie only in factory-programmed parameters (frequencies, stability, output format, supply voltage), not physical or electrical pin compatibility. PCB layout is fully reusable across the Si533 family.
