Product details
Overview
534DB000172DG 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 (with select options up to 1.4 GHz), ±20 ppm temperature stability, 3.3 V supply, and CML output format in an industry-standard 5 × 7 mm 8-pin package. It serves as a low-jitter clock source for FPGA/ASIC timing, SD/HD video systems, and high-speed serial data recovery.
For engineers reviewing the 534DB000172DG datasheet, 534DB000172DG pinout, 534DB000172DG application, or 534DB000172DG equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative oscillators, and supply-chain support details specific to this Si534 variant.
Technical Context
The 534DB000172DG 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 all-digital synthesis enables superior supply noise rejection and stable jitter performance across varying load and rail conditions.
Frequency selection is controlled via two logic-level pins (FS[1], FS[0]), each with internal 17 kΩ pull-up resistors to VDD, enabling hardware-selectable outputs without I²C or SPI configuration. Output enable (OE) supports tristate control, and the device powers up in enabled state with <10 ms oscillator stabilization time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Frequency Range | 10–945 MHz (any-rate); select frequencies up to 1400 MHz - supports flexible clock tree design without custom crystal sourcing |
| Output Format | CML - differential signaling with 1.1–1.9 VPP swing (2.5/3.3 V option), optimized for high-speed interconnects with low EMI |
| Supply Voltage | 3.3 V (±10%) - compatible with standard logic rails; IDD = 99–108 mA typical under load |
| Frequency Stability | ±20 ppm total (±20 ppm temp + ±10 ppm aging over 20 years) - ensures long-term timing accuracy in industrial environments |
| Phase Jitter (RMS) | 0.25–0.37 ps (12 kHz–80 MHz offset, FOUT > 500 MHz) - meets OC-192/SONET requirements for serial data recovery |
| Operating Temperature | –40 °C to +85 °C - qualified per MIL-STD-883 for reliability in telecom and networking equipment |
| Package | 5 × 7 mm, 8-pin surface-mount - industry-standard footprint with 2.54 mm pin pitch; RoHS-compliant, MSL1 |
Pinout & Package
534DB000172DG uses an 8-pin, 5 × 7 mm surface-mount package with exposed pad (not electrically connected). Pin 1 is marked by a dot; pin numbering follows top-view clockwise layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No connection (NC) | Unused; must be left floating or grounded per layout guidelines - no electrical function |
| 2 | Output Enable (OE) | Active-high control: OE = 0 disables CLK outputs into high-impedance state; internal 17 kΩ pull-up ensures default enabled operation |
| 3 | GND | Common reference for power and signal return - requires low-inductance connection to system ground plane |
| 4 | CLK+ | Differential positive output (CML) - delivers selected frequency with matched impedance (50 Ω to VDD – 1.3 V) |
| 5 | CLK– | Differential negative output (CML) - complements CLK+; 180° phase relationship required for proper termination |
| 6 | VDD | 3.3 V power supply - bypass with 0.1 µF ceramic capacitor near pin to suppress supply noise coupling into DSPLL core |
| 7 | FS[1] | Frequency Select MSB - selects one of four preprogrammed output frequencies; internal 17 kΩ pull-up simplifies control logic |
| 8 | FS[0] | Frequency Select LSB - used with FS[1] to encode 00/01/10/11 for quad-frequency selection |
Key Features
| Feature | Design Value |
|---|---|
| DSPLL® frequency synthesis | Enables four factory-programmed output frequencies from one internal crystal - eliminates BOM complexity and board space for multiple XOs |
| ±20 ppm total stability | Guarantees timing margin for SONET/SDH and Ethernet PHY applications over full temperature and lifetime without recalibration |
| CML output interface | Provides 1.5 VPP typical differential swing with <350 ps rise/fall time - supports >1 Gbps serial links with minimal jitter degradation |
| Hardware frequency selection | FS[1:0] pins allow deterministic, glitch-free frequency switching in <20 ms - no firmware or communication bus required |
| Industry-standard 5 × 7 mm package | Drop-in compatible with existing XO footprints and reflow profiles - reduces layout redesign risk for timing upgrades |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-output oscillator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si534AB000108DGR | Same Si534 family, LVPECL output, ±20 ppm stability, 3.3 V - differs in output format and programmed frequency set | Limited to LVPECL-compatible receivers; higher drive strength but greater power and EMI vs. CML | Select when interfacing with legacy PECL logic or when higher output swing (>1.9 VPP) is required |
| Si534CB000121DG | Same Si534 family, CMOS output, ±20 ppm stability, 3.3 V - limited to ≤160 MHz max frequency, lower power (81–88 mA) | Restricted to low-speed logic domains; unsuitable for >200 Mbps serial interfaces due to slew rate limits | Select only for cost-sensitive, low-frequency MCU or microcontroller clocking where differential signaling is unnecessary |
Compared with 534DB000172DG, Si534AB000108DGR offers higher output drive but requires stricter termination and consumes ~10% more current, while Si534CB000121DG trades frequency range and jitter performance for simplicity and lower power in non-high-speed applications.

FAQ
What output frequencies are programmed in the 534DB000172DG?
The 534DB000172DG is a factory-programmed quad-output oscillator with four specific frequencies determined by its six-digit configuration code "000172". Per Skyworks' ordering convention, this code maps to four unique frequencies within the 10–945 MHz band, selected at time of manufacture and documented in the device's configuration report. The exact values are not publicly decoded from the part number alone but are fixed and verified prior to shipment.
Does the 534DB000172DG require external configuration or programming after soldering?
No, the 534DB000172DG is fully factory-configured before shipment. All parameters - including the four output frequencies, CML output format, 3.3 V supply, ±20 ppm stability, and active-high OE polarity - are permanently programmed into the DSPLL core. No I²C, SPI, or other runtime configuration is needed or supported.
Can the 534DB000172DG operate with a 2.5 V supply instead of 3.3 V?
No, the 534DB000172DG is specifically configured for 3.3 V operation, as indicated by the "D" in its order code (per Skyworks' part numbering: D = 3.3 V, CML, high-OE). Using 2.5 V would violate the recommended operating condition (VDD min = 2.97 V for 3.3 V option) and may result in undefined behavior, failed startup, or degraded jitter performance.
How is frequency selection implemented on the 534DB000172DG?
Frequency selection on the 534DB000172DG is performed using two dedicated hardware pins: FS[1] (pin 7) and FS[0] (pin 8). These pins accept logic-level inputs (with internal 17 kΩ pull-ups to VDD) and encode four states (00, 01, 10, 11) to select among the four preprogrammed output frequencies. Switching occurs in under 20 ms with no glitches.
Is the 534DB000172DG pin-compatible with other Si534 variants like Si534AB000108DGR?
Yes, all Si534 devices - including 534DB000172DG and Si534AB000108DGR - share identical 8-pin, 5 × 7 mm package dimensions, pinout assignment, and mechanical footprint. Differences are limited to internal programming (frequency set, output format, voltage), so PCB layout and mounting are fully interchangeable.
