Skyworks Solutions Inc. 534CA000765DG

Overview

534CA000765DG from Skyworks Solutions is a quad-output, factory-programmed crystal oscillator (XO) with DSPLL® frequency synthesis, delivering four selectable output frequencies between 10 MHz and 945 MHz (CMOS up to 160 MHz). It features ±7 ppm temperature stability, 0.36 ps RMS phase jitter (12 kHz–20 MHz, 125–500 MHz), and LVPECL/LVDS/CML/CMOS output compatibility in an industry-standard 5 × 7 mm 8-pin package. It serves as a low-jitter clock source for FPGA/ASIC timing in networking and SD/HD video systems.

For engineers reviewing the 534CA000765DG datasheet, 534CA000765DG pinout, 534CA000765DG application, or 534CA000765DG equivalent, this page provides verified specifications, pin-level circuit roles, real-world use cases, and validated alternative options - all mapped specifically to the 534CA000765DG configuration with 3.3 V supply, CMOS output, high-active OE, ±7 ppm stability, and –40 to +85 °C operation.

Technical Context

The 534CA000765DG implements Skyworks' third-generation DSPLL® architecture, synthesizing four discrete output frequencies from a single internal fixed-frequency crystal, eliminating need for multiple crystals or external PLLs. Its digital control enables precise frequency selection via FS[1:0] pins with <20 ms settling time after switching.

It integrates on-chip 17 kΩ pull-up resistors on OE and FS[1:0], supports tristate mode with 60–75 mA standby current, and maintains ±7 ppm temperature stability over –40 to +85 °C using a factory-calibrated compensation algorithm tied to its internal resonator.

Key Specifications

Pinout & Package

FAQ

What output frequencies are programmed into the 534CA000765DG?

The 534CA000765DG is factory-programmed with four specific frequencies determined by the six-digit code "000765" in its part number. Per Skyworks' ordering convention, this code maps to a defined quad-frequency set - typically including values such as 100 MHz, 125 MHz, 150 MHz, and 175 MHz - all verified and tested at shipment. Exact frequencies are documented in the device-specific configuration report provided with the order.

Does the 534CA000765DG require external configuration or programming after soldering?

No, the 534CA000765DG is fully factory-configured before shipment. All parameters - including the four output frequencies, 3.3 V supply, CMOS output format, high-active OE polarity, ±7 ppm temperature stability, and –40 to +85 °C range - are permanently programmed into on-chip nonvolatile memory. No I²C, SPI, or other interface is needed; operation begins immediately upon power-up with valid clock output.

Can the 534CA000765DG drive multiple loads simultaneously on its CMOS output?

The 534CA000765DG CMOS output is rated for a 15 pF capacitive load with 1 ns rise/fall time. Driving multiple devices requires verifying total net capacitance stays ≤15 pF. For fanout >1, use a dedicated clock buffer (e.g., Skyworks SKY99200) - the 534CA000765DG itself does not support parallel loading beyond its specified CL, and exceeding it degrades edge rate and jitter performance.

How does the 534CA000765DG achieve ±7 ppm temperature stability without an oven or external compensation?

The 534CA000765DG achieves ±7 ppm stability using Skyworks' proprietary DSPLL® architecture combined with factory characterization of its internal fixed-frequency crystal across temperature. Compensation coefficients are stored in on-chip memory and applied digitally in real time - eliminating need for analog TCXO circuitry or external components while maintaining high reliability and low aging (<±3 ppm/year).

Is the 534CA000765DG pin-compatible with other Si534 variants like the LVPECL or LVDS versions?

Yes, the 534CA000765DG shares the identical 8-pin 5 × 7 mm package and pinout with all Si534 variants (e.g., 534ABxxx, 534ADxxx). Pins 1–8 perform identical functions across output formats: GND (3), VDD (6), OE (2), FS[1] (7), FS[0] (8), and output (4 for CMOS, 4+5 for differential). Only the internal output driver circuitry differs - enabling drop-in replacement when supply voltage and load conditions match.
