Product details

Overview

544BAHC002360BCGR from Skyworks Solutions is an I²C-programmable ultra-low-jitter crystal oscillator (XO) delivering 150 fs RMS phase jitter (12 kHz–20 MHz), factory-configured for 236.0 MHz output, ±7 ppm total frequency stability, and LVDS output format in a 3.2 × 5 mm CLCC package. It serves as a precision clock source for high-speed serial interfaces requiring deterministic timing integrity.

For engineers reviewing the 544BAHC002360BCGR datasheet, 544BAHC002360BCGR pinout, 544BAHC002360BCGR application, or 544BAHC002360BCGR equivalent, this device supports dynamic frequency reprogramming via I²C up to 1 Mbps, operates across –40 to +85 °C, and provides guaranteed PSNR of –83 dBc against 100–1000 kHz supply noise.

Technical Context

The 544BAHC002360BCGR implements Skyworks' 4th-generation DSPLL® architecture with a fixed 55.05 MHz crystal reference, fractional feedback divider (FBDIV), and cascaded HSDIV/LSDIV output dividers. Its digital loop filter and on-chip power supply regulation enable <1 ppb frequency resolution and robust immunity to VDD ripple.

It supports pin-selectable startup frequencies (dual or quad options), configurable OE/FS pin polarity and location, and operates from 1.8 V, 2.5 V, or 3.3 V supply-same part number, no hardware change required. Output enable time is ≤20 µs; power-up time is ≤10 ms.

Equivalent & Alternatives

The following parts are listed as comparable options for similar programmable XO applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice

FAQ

What is the factory-programmed output frequency of the 544BAHC002360BCGR?

The 544BAHC002360BCGR is factory-programmed for a 236.0 MHz startup frequency using LVDS output. This value is stored in non-volatile memory and persists across power cycles. The device retains full I²C reprogrammability to any frequency between 0.2 MHz and 1500 MHz, subject to LVDS bandwidth limits (≤1.4 GHz).

Does the 544BAHC002360BCGR support dual startup frequencies?

Yes, the 544BAHC002360BCGR supports two user-defined startup frequencies via the FS0 pin. When configured as a dual-frequency option (ordering code "E" or "F"), asserting FS0 selects the secondary frequency at power-up. Both frequencies are pre-programmed at the factory and require no I²C interaction to switch.

What is the maximum allowable supply voltage ripple for the 544BAHC002360BCGR?

The 544BAHC002360BCGR maintains –83 dBc PSNR against 50 mVpp sine-wave ripple at 100–1000 kHz. This specification is measured with a 156.25 MHz LVDS output and confirms stable operation even when powered directly from switched-mode supplies without additional filtering.

Can the 544BAHC002360BCGR be used with 1.8 V logic systems?

Yes, the 544BAHC002360BCGR operates from 1.8 V ±5% (1.71–1.89 V), supporting LVDS, CMOS, and HCSL outputs at that rail. Its internal regulation and noise rejection ensure consistent 150 fs jitter performance regardless of VDD level-no derating or configuration change is needed.

How is the OE pin configured on the 544BAHC002360BCGR?

Per the ordering code "A" in position 5 of 544BAHC002360BCGR, the OE pin is active-high and located on Pin 1. It features an internal 50 kΩ pull-up to VDD, enabling tristate operation within ≤3 µs after deassertion. No external pull-up resistor is required.
