Skyworks Solutions Inc. 562BAA002529BCGR

Overview

562BAA002529BCGR from Skyworks Solutions is an ultra-low-jitter quad-output crystal oscillator (XO) based on 4th-generation DSPLL® technology, delivering four factory-programmed frequencies from 0.2 to 3000 MHz with <1 ppb resolution and 90 fs RMS phase jitter (12 kHz–20 MHz). It supports LVPECL output, operates from 3.3 V supply, and is housed in a 5×7 mm CLCC package - designed for high-speed serial data clocking in 100G/400G OTN and coherent optical systems.

For engineers reviewing the 562BAA002529BCGR datasheet, 562BAA002529BCGR pinout, 562BAA002529BCGR application, or 562BAA002529BCGR equivalent, key selection criteria include its quad-frequency flexibility, guaranteed 20 ppm temperature stability over –40 to +85 °C, PSNR of –80 dBc typical, and support for frequency-select pin control (FS0/FS1) enabling dynamic output switching in FPGA/ASIC timing architectures.

Technical Context

The 562BAA002529BCGR implements a digital fractional-N DSPLL architecture with integrated DCO, digital phase detector, and loop filter - enabling precise synthesis of integer and fractional frequencies without external crystals per output. Its on-chip power regulation provides >80 dBc supply noise rejection, critical for operation alongside switched-mode power supplies in dense server and networking PCBs.

Frequency selection is controlled via two logic pins (FS0, FS1), allowing real-time switching among four pre-programmed outputs. The device integrates non-volatile memory (NVM) for permanent configuration storage and features built-in OE (output enable) functionality with configurable polarity and pin location - all factory-set at shipment.

FAQ

What output format and supply voltage does the 562BAA002529BCGR support?

The 562BAA002529BCGR is configured for LVPECL output and operates exclusively from a 3.3 V ±5% supply. It does not support 1.8 V or 2.5 V operation, nor alternative formats like LVDS or CMOS - this configuration is factory-programmed and immutable. The 562BAA002529BCGR datasheet specifies LVPECL swing (1.1–1.9 VPP for FCLK < 1.5 GHz) and common-mode voltage (VDD – 1.42 to VDD – 1.25 V), requiring Thevenin or VTT termination per Figure 4.1.

How are the four frequencies selected on the 562BAA002529BCGR?

The 562BAA002529BCGR uses two dedicated pins - FS0 (Pin 8) and FS1 (Pin 7) - to select among its four factory-programmed frequencies. The combination FS[1:0] = 00, 01, 10, or 11 determines which output is active, with settling time ≤10 ms after change. These pins accept standard CMOS logic levels (VIH ≥ 0.7×VDD, VIL ≤ 0.3×VDD) and include internal 50 kΩ pull-ups to VDD, so tying them to GND selects specific frequencies while leaving them open defaults to FS[1:0] = 11.

Does the 562BAA002529BCGR require external configuration or I²C programming?

No, the 562BAA002529BCGR is fully factory-configured - all parameters including the four frequencies, output format (LVPECL), supply voltage (3.3 V), OE polarity (active-high on Pin 1), and package (5×7 mm) are permanently stored in on-chip NVM. No external programming, I²C interface, or configuration EEPROM is needed. The 562BAA002529BCGR powers up ready to operate with only VDD, GND, and proper termination applied.

What is the thermal performance of the 562BAA002529BCGR in its 5×7 mm package?

In the 5×7 mm CLCC package, the 562BAA002529BCGR has a thermal resistance junction-to-ambient (ΘJA) of 53 °C/W under still-air conditions (85 °C ambient), and junction-to-board (ΨJB) of 26 °C/W. This enables reliable operation at full load (max IDD ≈ 160 mA for LVPECL) without forced airflow, provided the PCB uses at least two 0.3 mm vias per GND pad and follows Skyworks' land pattern guidelines (Table 6.1). Derating is recommended above 85 °C ambient.

Can the 562BAA002529BCGR be used in place of a traditional single-output XO?

Yes - the 562BAA002529BCGR can directly replace a single-output XO by using only one of its four frequencies (e.g., FS[1:0] hardwired to 00), while retaining all benefits: identical 5×7 mm footprint, same pinout compatibility (CLK+, CLK−, VDD, GND, OE), and superior jitter (90 fs vs. typical 200–500 fs for legacy XOs). Its OE pin also adds hardware clock gating unavailable in most standard XOs, enhancing power management in the 562BAA002529BCGR's target applications.
