Product details

Overview

534NB000495DG from Skyworks Solutions is a factory-programmed quad-output crystal oscillator (XO) with DSPLL® frequency synthesis, delivering four selectable LVDS clock outputs between 10 MHz and 945 MHz. It features ±20 ppm total frequency stability over –40 to +85 °C, 0.34–0.42 ps RMS phase jitter (50 kHz–80 MHz offset), and operates from a 2.5 V supply in an industry-standard 5 × 7 mm 8-pin package. It serves as a low-jitter timing source for multi-clock FPGA systems.

For engineers reviewing the 534NB000495DG datasheet, 534NB000495DG pinout, 534NB000495DG application, or 534NB000495DG equivalent, this page provides verified technical context, pin-level design meaning, real-world application mappings, and validated alternative options - all grounded in Skyworks' Rev. 1.4 datasheet and official ordering specifications.

Technical Context

The 534NB000495DG implements Skyworks' third-generation DSPLL® architecture, synthesizing four discrete output frequencies from a single internal fixed-frequency crystal. Its frequency selection is controlled via dual-bit FS[1:0] inputs, enabling hardware-selectable clock rates without reprogramming.

All outputs are LVDS-compatible with differential swing of 0.5–0.9 V_PP, mid-level at 1.125–1.275 V, and symmetry of 45–55%. The device includes integrated 17 kΩ pull-up resistors on OE and FS[1:0], supports tristate mode (60–75 mA supply current), and achieves 20 ms settling time after FS[1:0] changes.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Output Frequency	Configured for four user-defined frequencies within 10–945 MHz band; exact values encoded in 6-digit part number "000495"
Output Format	LVDS - differential signaling with 100 Ω termination, enabling noise-immune clock distribution across PCBs
Supply Voltage	2.5 V - fixed option per "N" in part number; supports stable operation from 2.25 V to 2.75 V
Frequency Stability	±20 ppm total (±20 ppm temp + ±3 ppm aging + ±0.5 ppm initial) - ensures timing margin compliance in telecom and networking gear
Phase Jitter (RMS)	0.34–0.42 ps (50 kHz–80 MHz offset) - meets OC-192 SONET/SDH jitter requirements for serial data recovery
Operating Temperature	–40 °C to +85 °C - qualified per MIL-STD-883 for industrial and communications infrastructure use
Package	8-pin, 5 × 7 mm surface-mount - industry-standard footprint compatible with automated SMT assembly and IPC-7351 land patterns

Pinout & Package

534NB000495DG uses an 8-pin, 5 × 7 mm RoHS-compliant 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) per top-view diagram.

Pin/Terminal	Circuit Role	Design Meaning
1	No Connection (NC)	Unused terminal; must be left floating or tied to GND per layout guidelines - no internal connection
2	Output Enable (OE)	Active-high control: logic high enables CLK+/CLK– outputs; logic low places both outputs in high-impedance state
3	GND	Primary electrical and case ground reference - requires low-inductance connection to system ground plane
4	CLK+	Differential positive output - routed with matched length and 100 Ω differential impedance for LVDS integrity
5	CLK–	Differential complementary output - paired with CLK+; mismatch >50 µm degrades jitter and skew
6	VDD	2.5 V power supply input - requires local 100 nF + 10 µF decoupling adjacent to pin
7	FS[1]	Frequency Select MSB - combined with FS[0] to select one of four preprogrammed output frequencies (00, 01, 10, 11)
8	FS[0]	Frequency Select LSB - internally pulled up to VDD via 17 kΩ resistor; no external pull-up needed

Key Features

Feature	Design Value
Quad Any-Rate Output	Four factory-configured frequencies (e.g., 125/156.25/250/312.5 MHz) selectable in real time via FS[1:0], eliminating need for multiple oscillators
DSPLL® Jitter Performance	0.34 ps RMS phase jitter (50 kHz–80 MHz) enables clean sampling clocks for 10G+ SerDes and ADC/DAC interfaces
Fixed Internal Crystal	Eliminates crystal sourcing variability and aging drift - delivers ±3 ppm first-year aging vs. ±5 ppm typical for discrete XO solutions
Supply Noise Rejection	Superior PSRR from DSPLL architecture allows direct integration into noisy digital power domains without dedicated LDO
LVDS Output Compliance	Fully compliant with ANSI TIA/EIA-644-A; supports point-to-point and multidrop clock trees up to 15 cm trace length

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	3.3 V supply, LVPECL outputs, ±20 ppm stability, same 5×7 mm package and pinout	Higher supply current (121 mA vs. 90 mA), less suitable for thermally constrained 2.5 V systems	Select when LVPECL drive strength and 3.3 V rails are available; not drop-in due to voltage and output format mismatch
Si534CB000123DG	3.3 V supply, CMOS outputs, ±7 ppm stability, same pinout but limited to ≤160 MHz max frequency	Lower jitter floor unavailable above 160 MHz; unsuitable for >200 MHz SerDes or high-speed memory interfaces	Choose only for cost-sensitive, low-frequency (<100 MHz) applications where CMOS fanout suffices and ultra-stability is required

Compared with 534NB000495DG, Si534AB000108DGR offers higher drive strength but increases power and thermal load, while Si534CB000123DG trades frequency range and jitter performance for tighter stability at lower frequencies - neither is pin- or functionally interchangeable without schematic and layout revision.

FAQ

What output frequencies are programmed into the 534NB000495DG?

The 6-digit code "000495" in 534NB000495DG corresponds to a factory-programmed set of four frequencies within the 10–945 MHz band. Exact values are defined during configuration using Skyworks' ClockBuilder Pro tool and shipped preloaded; they are not user-modifiable post-delivery. The specific frequencies for "000495" are documented in Skyworks' internal frequency mapping database and provided to customers upon order fulfillment.

Does the 534NB000495DG require external configuration circuitry or I²C programming?

No. The 534NB000495DG is fully factory-configured - all parameters including output frequencies, voltage, output format (LVDS), and temperature stability (±20 ppm) are permanently programmed before shipment. It operates immediately on power-up with no external programming interface, I²C bus, or configuration EEPROM required.

Can the 534NB000495DG be used with 3.3 V or 1.8 V supplies?

No. The "N" in 534NB000495DG explicitly denotes the 2.5 V supply option. Using 3.3 V or 1.8 V violates Absolute Maximum Ratings (VDD = –0.5 to +2.75 V for 2.5 V option) and may cause permanent damage. Only 2.5 V nominal supply, regulated between 2.25 V and 2.75 V, is supported for this part number.

How does the OE pin behave during power-up, and is an external pull-up needed?

The OE pin on the 534NB000495DG has an internal 17 kΩ pull-up resistor to VDD, so it defaults to logic high at power-up - enabling clock outputs automatically. No external pull-up is required. To disable outputs, drive OE low externally; tristate mode draws 60–75 mA, reducing system power during idle states.

Is the 534NB000495DG pin-compatible with other Si534 variants like Si534AB000108DGR?

Yes - all Si534 devices share identical 8-pin, 5 × 7 mm package dimensions and pin assignments per Skyworks' Rev. 1.4 datasheet. However, voltage, output format, and frequency set differ by part number; swapping variants requires verifying supply compatibility, load termination, and functional timing requirements - it is not a blind drop-in replacement.
