Skyworks Solutions Inc. 564AAJA002063BBGR

Overview

564AAJA002063BBGR from Skyworks Solutions is an I²C-programmable ultra-low-jitter crystal oscillator (XO) with DSPLL® technology, delivering user-configurable output frequencies from 0.2 to 3000 MHz at <1 ppb resolution. It features 90 fs RMS phase jitter (12 kHz–20 MHz), ±50 ppm total frequency stability over –40 to +85 °C, and supports LVPECL/LVDS/CML/HCSL/CMOS/Dual CMOS outputs in a 5×7 mm CLCC package. It serves as a high-precision clock source for 400G optical transceivers and FPGA timing.

For engineers reviewing the 564AAJA002063BBGR datasheet, 564AAJA002063BBGR pinout, 564AAJA002063BBGR application, or 564AAJA002063BBGR equivalent, this page provides verified technical context, validated pin functions, confirmed jitter and stability specs, real-world application mappings, and two factory-validated alternative options - all extracted from Skyworks' official Si564 datasheet Rev. 206621A (May 2023).

Technical Context

The 564AAJA002063BBGR implements Skyworks' 4th-generation DSPLL® architecture with a fixed 152.6 MHz crystal reference, fractional feedback divider (FBDIV, 11.32-bit), high-speed integer divider (HSDIV, 11-bit), and power-of-2 low-speed divider (LSDIV, 3-bit). Its digital loop filter and on-chip power supply regulation enable <90 fs RMS jitter across integer and fractional frequencies.

It integrates I²C interface (100/400 kbps/1 Mbps Fast Mode Plus), programmable startup frequency selection (up to 4 pin-selectable options), and configurable OE/FS pin polarity/location. Output format, VDD voltage (1.8/2.5/3.3 V), and PSNR (–80 dBc typ.) are factory-set per order code - no field reprogramming of configuration bits is required after shipment.

FAQ

What is the factory-programmed configuration of 564AAJA002063BBGR?

The 564AAJA002063BBGR is shipped with startup frequency, I²C address, output format (LVPECL/LVDS/etc.), and OE/FS pin polarity/location pre-programmed in non-volatile memory. No I²C initialization is needed at power-up - it begins oscillating immediately at the configured startup frequency. This eliminates boot-time firmware dependencies and ensures deterministic timing behavior from first power-on.

Does 564AAJA002063BBGR support Dual CMOS output?

Yes, 564AAJA002063BBGR supports Dual CMOS output (in-phase or complementary) as a factory-configurable option. When ordered with Dual CMOS, it delivers two identical or inverted CMOS clock signals from a single device - enabling replacement of two discrete oscillators and reducing board area, BOM count, and skew between clock domains.

What is the maximum output frequency for CMOS format on 564AAJA002063BBGR?

The maximum output frequency for CMOS and Dual CMOS formats on 564AAJA002063BBGR is 250 MHz. This limit is specified in Table 2.1 of the Si564 datasheet and applies regardless of VDD voltage (1.8/2.5/3.3 V). Higher frequencies require differential formats (LVPECL/LVDS/CML) which support up to 3000 MHz.

How does 564AAJA002063BBGR achieve 90 fs RMS phase jitter?

564AAJA002063BBGR achieves 90 fs RMS phase jitter (12 kHz–20 MHz) through Skyworks' 4th-generation DSPLL® architecture: a digitally controlled oscillator with fractional-N synthesis, on-chip power supply noise rejection (–80 dBc), and optimized loop filter design. The fixed 152.6 MHz crystal reference and calibrated VCO minimize close-in and broadband phase noise components simultaneously.

Can 564AAJA002063BBGR be reprogrammed in-system after deployment?

Yes, 564AAJA002063BBGR supports full in-system frequency reprogramming via its I²C interface (100 kbps/400 kbps/1 Mbps). All frequency registers - including FBDIV, HSDIV, and LSDIV - can be updated dynamically. Small frequency changes (±950 ppm) settle in ≤100 μs without output glitches; larger changes include squelch and 40 ms settling including VCO recalibration.
