Skyworks Solutions Inc. 532NA000242DGR

Overview

532NA000242DGR from Skyworks Solutions is a dual-frequency, factory-programmed crystal oscillator (XO) with DSPLL® clock synthesis, delivering two selectable output frequencies in the 10 MHz to 945 MHz range. It features LVPECL output, 3.3 V supply, ±20 ppm total frequency stability over –40 to +85 °C, and 0.26 ps typical RMS phase jitter (50 kHz–80 MHz, OC-192). It serves as a low-jitter timing source for FPGA clocking and high-speed serial data recovery.

For engineers reviewing the 532NA000242DGR datasheet, 532NA000242DGR pinout, 532NA000242DGR application, or 532NA000242DGR equivalent, key selection criteria include dual-frequency switching via FS pin, tristate control via OE, industry-standard 5 × 7 mm 6-pin package, and compatibility with noise-sensitive communication subsystems requiring sub-0.4 ps jitter performance.

Technical Context

The 532NA000242DGR implements Skyworks' third-generation DSPLL® architecture, synthesizing both output frequencies from a single internal fixed-crystal reference to ensure high reliability and low aging. Its dual-frequency capability is controlled by the FS pin, enabling real-time switching between two factory-programmed frequencies without external reconfiguration.

It integrates on-chip supply noise rejection optimized for noisy digital environments, supports LVPECL output with 1.1–1.9 V_PP differential swing, and achieves <10 ms settling time after FS transition. The device operates across –40 to +85 °C with 121 mA typical supply current under LVPECL load at 3.3 V.

FAQ

What output frequencies are programmed into the 532NA000242DGR?

The 532NA000242DGR is factory-programmed with two specific frequencies determined by its six-digit frequency designator "000242". Per Skyworks' part numbering convention, this code corresponds to two frequencies within the 10–945 MHz band-typically one lower and one higher value-selected at order time. Exact values are documented in the device-specific configuration report provided with shipment and can be verified using Skyworks' ClockBuilder Pro tool.

Does the 532NA000242DGR support LVDS or CMOS output formats?

No, the 532NA000242DGR is configured exclusively for LVPECL output, as indicated by the "A" in the 2nd option code position of its part number. While the Si532 family supports LVDS, CMOS, and CML, this specific variant (532NA000242DGR) has LVPECL drivers and requires 50 Ω termination to VDD – 2.0 V. Using it with LVDS or CMOS loads would violate output specifications and degrade jitter performance.

How does the Frequency Select (FS) pin function on the 532NA000242DGR?

The FS pin on the 532NA000242DGR is a logic input that selects between its two factory-programmed output frequencies: FS = 0 enables the first frequency, FS = 1 enables the second. It features an internal 17 kΩ pull-up resistor to VDD, so an unconnected or high state defaults to the second frequency. Switching occurs within 10 ms, and the pin tolerates standard 3.3 V CMOS logic levels.

What is the supply current consumption of the 532NA000242DGR under typical operating conditions?

The 532NA000242DGR draws 111 mA typical and 121 mA maximum supply current when enabled and driving LVPECL loads at 3.3 V, per Table 1 in the datasheet. In tristate mode (OE = 0), current drops to 60–75 mA. This current rating assumes operation at +25 °C; derating applies above 70 °C ambient, and actual draw depends on output loading and frequency.

Is the 532NA000242DGR compliant with RoHS and lead-free soldering standards?

Yes, the 532NA000242DGR is Pb-free and RoHS-compliant, as confirmed by its "R" suffix (Tape & Reel) and the "+" mark on the top-side marking per Table 12. It meets JEDEC J-STD-020C MSL1 classification and supports Pb-free reflow with peak temperature of 260 °C for 20–40 seconds-fully compatible with standard lead-free manufacturing processes.
