Skyworks Solutions Inc. 534SC000618DG

Overview

534SC000618DG from Skyworks Solutions is a quad-output, factory-programmed crystal oscillator (XO) with DSPLL® clock synthesis, delivering four selectable frequencies between 10 MHz and 945 MHz. It features LVDS output, 3.3 V supply, ±7 ppm temperature stability, and operates across –40 to +85 °C. Used in FPGA/ASIC clock generation and SD/HD video timing systems where low-jitter, multi-frequency synchronization is required.

For engineers reviewing the 534SC000618DG datasheet, 534SC000618DG pinout, 534SC000618DG application, or 534SC000618DG equivalent, key selection criteria include output format compatibility (LVDS), frequency select logic behavior, tristate enable timing, and thermal performance under industrial ambient conditions.

Technical Context

The 534SC000618DG implements Skyworks' third-generation DSPLL® architecture to synthesize precise output frequencies from a single internal fixed-frequency crystal, eliminating need for multiple crystals. Its four-frequency selection is controlled via dual-bit FS[1:0] inputs with internal 17 kΩ pull-up resistors to VDD.

It supports LVDS differential outputs with 100 Ω termination, delivers phase jitter as low as 0.36 ps RMS (12 kHz–20 MHz, 125–500 MHz range), and achieves total frequency stability of ±20 ppm including aging and temperature effects. Powerup time is ≤10 ms, and frequency switching settles within 20 ms after FS[1:0] change.

FAQ

What output format and supply voltage does the 534SC000618DG use?

The 534SC000618DG uses LVDS output format and is configured for 3.3 V operation. Its LVDS outputs meet JEDEC JESD8-12 specifications with 100 Ω differential termination, and it draws 90–98 mA typical supply current. The part number suffix 'C' confirms CMOS-compatible logic levels for OE and FS inputs, while 'S' indicates LVDS output and 'D' denotes ±7 ppm temperature stability.

How many output frequencies does the 534SC000618DG support, and how are they selected?

The 534SC000618DG supports four factory-programmed output frequencies, selected via the two-bit FS[1:0] control interface. FS[1] (pin 7) and FS[0] (pin 8) are internally pulled up to VDD with 17 kΩ resistors, ensuring defined states when left unconnected. Frequency switching completes within 20 ms after FS[1:0] changes, and the specific frequencies are encoded in the six-digit code '000618' per Skyworks' ordering convention.

What is the phase jitter performance of the 534SC000618DG at its typical operating frequencies?

The 534SC000618DG delivers 0.36 ps RMS phase jitter (typical) over the 12 kHz–20 MHz offset range for output frequencies between 125 MHz and 500 MHz. At 622.08 MHz, typical phase noise is –134 dBc/Hz at 1 MHz offset. These values are measured under standard conditions (TA = 25 °C, VDD = 3.3 V) and meet OC-48 and OC-192 jitter compliance requirements for telecom applications.

Does the 534SC000618DG require an external crystal or configuration circuitry?

No, the 534SC000618DG does not require an external crystal or configuration circuitry. It integrates a fixed-frequency crystal resonator and DSPLL® synthesis circuitry internally. All configuration-including output frequencies, voltage, and stability-is factory-programmed and permanently stored. Only OE and FS[1:0] control signals need external connection; no I²C, SPI, or programming interface is present.

What is the thermal and environmental qualification status of the 534SC000618DG?

The 534SC000618DG is qualified per MIL-STD-883 for mechanical shock, vibration, and solderability, and meets J-STD-020 MSL1 moisture sensitivity level. Its thermal resistance is θJA = 84.6 °C/W (still air), and it operates safely up to 125 °C junction temperature. The device uses gold-over-nickel contact pads and is Pb-free/RoHS-compliant, with a maximum storage temperature of +125 °C and ESD rating of 2000 V HBM.
