Skyworks Solutions Inc. 534BB002505DG

Overview

534BB002505DG 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 ±20 ppm temperature stability, LVDS output format, and operates from a 3.3 V supply across –40 to +85 °C. Used in high-speed networking and FPGA clocking where low-jitter, multi-frequency timing is required.

For engineers reviewing the 534BB002505DG datasheet, 534BB002505DG pinout, 534BB002505DG application, or 534BB002505DG equivalent, this page provides verified electrical specs, pin-level functional roles, real-world use cases, and validated alternative options for timing-critical embedded and communications systems.

Technical Context

The 534BB002505DG implements Skyworks' third-generation DSPLL® architecture to synthesize precise output frequencies from a single internal fixed-frequency crystal, eliminating need for multiple crystals or external PLLs. Its frequency selection is controlled via two digital inputs (FS[1:0]), enabling dynamic switching among four pre-programmed outputs without reconfiguration delay.

It supports LVDS differential signaling with 0.5–0.9 V_PP swing, 45–55% duty cycle symmetry, and delivers sub-0.5 ps RMS phase jitter (12 kHz–20 MHz integration band) at frequencies >500 MHz. The device includes integrated 17 kΩ pull-up resistors on OE and FS pins and enters tristate mode when OE is low.

FAQ

What output frequencies are programmed into the 534BB002505DG?

The 534BB002505DG is factory-programmed with four specific output frequencies determined by its six-digit frequency designator "002505". Per Skyworks' ordering convention, this code corresponds to a defined quad-frequency set - typically including values such as 156.25 MHz, 312.5 MHz, 625 MHz, and 1.25 GHz - all within the 10–945 MHz range and optimized for SONET/SDH and Ethernet applications. Exact values are documented in the device's configuration certificate.

Does the 534BB002505DG support CMOS output?

No, the 534BB002505DG does not support CMOS output. Its second option code "B" specifies LVDS output format, confirmed by Skyworks' part numbering matrix and electrical specifications. CMOS is only available for option codes C, G, and J - and limited to ≤160 MHz. Using this device with CMOS-requiring loads would require external level translation.

What is the power-up time for the 534BB002505DG?

The 534BB002505DG has a maximum power-up time of 10 ms - defined as the time from VDD reaching valid operating voltage to stable output frequency (f_O) at the CLK+/CLK– pins. This specification applies across all supply voltages (1.8 V, 2.5 V, 3.3 V) and output formats, and is measured under recommended operating conditions per Table 1 in the datasheet.

Can the 534BB002505DG be used in place of a traditional single-output XO?

Yes, the 534BB002505DG can replace a single-output XO by using only one of its four pre-programmed frequencies - for example, holding FS[1:0] at a fixed state (e.g., 00) to select the primary output. Its pin-compatible footprint and identical 5×7 mm package allow drop-in substitution in existing layouts, provided OE is held high and unused FS pins are terminated appropriately.

Is the 534BB002505DG RoHS-compliant and lead-free?

Yes, the 534BB002505DG is Pb-free and RoHS-compliant, as indicated by the "+" mark on the top-side laser marking and confirmed in Table 7 of the datasheet. It meets JEDEC J-STD-020C MSL1 moisture sensitivity classification and supports standard Pb-free reflow profiles with peak temperature of 260 °C for 20–40 seconds.
