Skyworks Solutions Inc. 534AB002364DG

Overview

534AB002364DG from Skyworks Solutions is a factory-programmed quad-output crystal oscillator (XO) delivering four selectable frequencies in the 10 MHz to 945 MHz range, with ±20 ppm temperature stability and LVDS output format at 3.3 V supply. It uses DSPLL® synthesis for low-jitter clock generation and supports frequency selection via FS[1:0] pins. This device serves as a timing source in high-speed serial interfaces requiring stable multi-frequency clocks.

For engineers reviewing the 534AB002364DG datasheet, 534AB002364DG pinout, 534AB002364DG application, or 534AB002364DG equivalent, key selection criteria include its quad-frequency capability, LVDS output compatibility, ±20 ppm total stability over –40 to +85 °C, tristate-enabled OE control, and industry-standard 5 × 7 mm 8-pin package.

Technical Context

The 534AB002364DG implements third-generation DSPLL® circuitry to synthesize any-rate output frequencies from a single fixed internal crystal, eliminating need for multiple crystals per frequency. Its architecture provides superior supply noise rejection and enables sub-0.4 ps RMS phase jitter performance across OC-48 and OC-192 integration bands.

Frequency selection is controlled by two logic inputs (FS[1], FS[0]) with internal 17 kΩ pull-up resistors to VDD, enabling four discrete output frequencies without external configuration. The device operates with LVDS differential outputs referenced to 1.2 V mid-level, supporting 100 Ω differential termination and delivering 0.5–0.9 VPP swing with 45–55% duty cycle symmetry.

FAQ

What output frequencies are programmed into the 534AB002364DG?

The 534AB002364DG is factory-programmed with four specific frequencies within the 10–945 MHz range, determined by the six-digit frequency designator "002364" in its part number. Per Skyworks' ordering convention, this code maps to defined frequency pairs; exact values are specified in the device's configuration record and shipped calibration report. The 534AB002364DG does not allow field reprogramming - all frequencies are set at manufacture.

Does the 534AB002364DG support CMOS output?

No, the 534AB002364DG does not support CMOS output. Its part number suffix "AB" indicates LVDS output format with 3.3 V supply. CMOS variants use suffixes "AC", "AG", "AJ", or "AV" per Skyworks' ordering guide. Attempting to operate the 534AB002364DG as CMOS would violate output stage specifications and risk signal integrity failure.

What is the power-up time specification for the 534AB002364DG?

The 534AB002364DG has a maximum power-up time of 10 ms - defined as the interval from VDD reaching valid operating voltage to CLK± outputs achieving stable nominal frequency and amplitude. This value applies under all supply voltages and temperature conditions within the –40 to +85 °C range, and is independent of OE or FS[1:0] state transitions.

Can the 534AB002364DG be used in place of a traditional single-output XO?

Yes, the 534AB002364DG can replace a single-output XO by fixing FS[1:0] to a constant logic level (e.g., 00) and using only one of its four outputs. Its LVDS output, ±20 ppm stability, and 3.3 V supply match common XO requirements. However, unused FS and OE pins must still be properly terminated per datasheet guidance to avoid floating inputs and ensure robust operation of the 534AB002364DG.

Is the 534AB002364DG RoHS-compliant and Pb-free?

Yes, the 534AB002364DG is RoHS-compliant and Pb-free, as confirmed by its "+" mark on the top-side marking per Skyworks' Si534 Mark Specification (Rev. 1.4, page 9). It meets JEDEC J-STD-020C MSL1 moisture sensitivity classification and supports Pb-free reflow profiles with peak temperature of 260 °C for 20–40 seconds - fully compliant with modern electronics manufacturing standards.
