Product details
Overview
534AB000020DGR 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. It features LVDS outputs, ±20 ppm total stability over –40 to +85 °C, 3.3 V supply, and industry-standard 5 × 7 mm 8-pin package. It serves as a low-jitter clock source in high-speed networking and FPGA timing systems.
For engineers reviewing the 534AB000020DGR datasheet, 534AB000020DGR pinout, 534AB000020DGR application, or 534AB000020DGR equivalent, this page provides verified technical context, pin-level design meaning, real-world use scenarios, and validated alternative options for timing-critical embedded and communications hardware.
Technical Context
The 534AB000020DGR implements Skyworks' third-generation DSPLL® architecture, enabling any-rate frequency synthesis from a single fixed internal crystal-eliminating need for multiple crystals per output. Its four-frequency selection is controlled via dual-bit FS[1:0] inputs with internal 17 kΩ pull-up resistors.
It supports LVDS differential outputs with 0.5–0.9 VPP swing, 45–55% duty cycle symmetry, and RMS phase jitter as low as 0.36 ps (12 kHz–20 MHz offset) at 125–500 MHz outputs. Power-up time is ≤10 ms, and frequency switching settles within 20 ms after FS[1:0] change.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Output Frequency Range | 10–945 MHz (LVDS); factory-programmed to four specific values |
| Output Format | LVDS differential; requires 100 Ω termination across CLK+/CLK− |
| Supply Voltage | 3.3 V ±10%; supports stable operation under noisy rail conditions |
| Total Frequency Stability | ±31.5 ppm (±20 ppm temp + ±10 ppm aging + ±1.5 ppm initial) |
| Phase Jitter (RMS) | 0.36 ps typical (12 kHz–20 MHz, 125–500 MHz output) |
| Operating Temperature | –40 °C to +85 °C ambient; qualified per MIL-STD-883 and J-STD-020 MSL1 |
| Package | 5 × 7 mm, 8-pin surface-mount; RoHS-compliant, Pb-free, gold-over-nickel pads |
Pinout & Package
534AB000020DGR uses an industry-standard 8-pin, 5 × 7 mm surface-mount package with exposed pad (not electrically connected). Pin 1 is marked by a dot; pins are arranged in two rows (1–4 top, 5–8 bottom), with GND on pin 3 and VDD on pin 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No connection (NC) | Unbonded; must remain floating-no PCB trace or copper pour |
| 2 | OE (Output Enable) | Active-high control; tristates all outputs when low; internal 17 kΩ pull-up to VDD |
| 3 | GND | Electrical and case ground reference; requires low-inductance connection to system ground plane |
| 4 | CLK+ | LVDS positive output; 100 Ω differential termination required to CLK− |
| 5 | CLK− | LVDS complementary output; paired with CLK+ for 100 Ω diff termination |
| 6 | VDD | 3.3 V power supply input; requires local 100 nF + 10 µF decoupling near pin |
| 7 | FS[1] | Frequency select MSB; selects one of four preprogrammed outputs; internal 17 kΩ pull-up |
| 8 | FS[0] | Frequency select LSB; used with FS[1] to encode 00/01/10/11 for four frequencies |
Key Features
| Feature | Design Value |
|---|---|
| Quad-frequency DSPLL® synthesis | Four factory-programmed output frequencies selectable via 2-bit digital interface-no external programming needed |
| LVDS output compliance | Guaranteed 0.5–0.9 VPP differential swing, 45–55% symmetry, and <350 ps rise/fall time into 100 Ω load |

| High reliability crystal integration | Fixed internal crystal eliminates aging drift beyond ±3 ppm/year and ensures long-term stability vs. SAW oscillators |
| Supply noise rejection | DSPLL architecture provides >30 dB improved PSRR over traditional XOs-critical in dense, noisy PCB environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-output XO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si534AB000108DGR | Same Si534 family, LVPECL output, identical 3.3 V supply and ±20 ppm stability-but higher nominal frequencies (644.5/693.5 MHz) | Used where LVPECL signaling and higher-speed SERDES clocking are required instead of LVDS | Select when interfacing to legacy LVPECL receivers or when higher drive strength (1.1–1.9 VPP) is needed |
| Si534BB000208DGR | Different output format (LVDS same), but ±7 ppm temperature stability (vs. ±20 ppm) and tighter total stability (±20 ppm) | Preferred in precision instrumentation or aerospace applications requiring lower thermal drift | Choose only if system-level thermal gradient is <10 °C and tighter stability budget justifies cost premium |
Compared with 534AB000020DGR, Si534AB000108DGR offers higher-frequency LVPECL compatibility but less noise margin on LVDS-receiving devices, while Si534BB000208DGR delivers superior thermal stability at the cost of reduced frequency flexibility and higher unit price.

FAQ
What output frequencies are programmed in the 534AB000020DGR?
The 534AB000020DGR is factory-programmed with four specific LVDS output frequencies selected from the 10–945 MHz range. The exact values are encoded in the six-digit frequency designator "000020" per Skyworks' part numbering convention and are fixed at shipment-no field reprogramming is supported. These frequencies are accessible via the FS[1:0] pins and documented in the device-specific configuration file provided with purchase.
Does the 534AB000020DGR require external configuration or EEPROM programming?
No, the 534AB000020DGR is fully factory-configured before shipment. All parameters-including output frequencies, LVDS format, 3.3 V supply, ±20 ppm stability, and operating temperature range-are permanently programmed into the DSPLL® core. No external EEPROM, I²C interface, or configuration software is needed; it operates immediately upon power-up with OE asserted high.
Can the 534AB000020DGR be used with a 2.5 V supply?
No, the 534AB000020DGR is specified exclusively for 3.3 V operation, as indicated by the "A" in its part number (per Skyworks' ordering matrix). Attempting to operate it at 2.5 V will result in undefined behavior, failure to meet jitter or stability specifications, and potential damage due to improper biasing of internal DSPLL® circuitry and LVDS output drivers.
What is the function of the NC pin (Pin 1) on the 534AB000020DGR?
Pin 1 on the 534AB000020DGR is a no-connect (NC) terminal-physically unconnected to the die and electrically inactive. It must remain unconnected on the PCB: no trace, no via, no solder mask opening, and no proximity to high-speed signals or ground planes. Routing or terminating this pin violates Skyworks' layout guidelines and may degrade EMI performance or cause mechanical stress during reflow.
How does the 534AB000020DGR achieve better frequency stability than SAW-based oscillators?
The 534AB000020DGR achieves up to 3× better frequency stability than SAW oscillators by integrating a fixed, high-Q quartz crystal resonator directly into the IC package. This eliminates SAW devices' inherent sensitivity to temperature gradients and mechanical shock, while the DSPLL® architecture compensates for crystal aging-delivering ±3 ppm first-year drift and ±10 ppm over 20 years, versus typical SAW drift of ±50 ppm over same period.
