Product details

Overview

512CAA000210AAG from Skyworks Solutions is a dual-frequency, factory-programmed crystal oscillator (XO) with CMOS output, 3.3 V supply, ±30 ppm total stability, and two user-selectable frequencies - 100 MHz and 212.5 MHz - configured via the FS pin. It operates across –40 to +85 °C in a 3.2 × 5.0 mm 6-pin package and serves as a low-jitter clock source for FPGA/ASIC timing and high-speed serial interfaces.

For engineers reviewing the 512CAA000210AAG datasheet, 512CAA000210AAG pinout, 512CAA000210AAG application, or 512CAA000210AAG equivalent, this device supports frequency switching under system control, offers integrated runt suppression on OE and power-on, includes on-chip LDO filtering for supply noise rejection, and delivers sub-1 ps RMS period jitter at 156.25 MHz in CMOS mode.

Technical Context

The 512CAA000210AAG implements Skyworks' DSPLL® synthesis architecture using a single fixed-crystal reference and an all-digital PLL to generate any frequency from 100 kHz to 212.5 MHz (CMOS limit). Its dual-frequency capability is controlled by a single digital FS input, enabling dynamic clock selection without external components.

It integrates an on-chip LDO regulator for enhanced supply noise rejection, supports active-high OE with internal pull-up, and features runt suppression on both OE assertion and power-up to prevent spurious clock edges. The device is factory-configured - no in-system programming required.

Key Specifications

Pinout & Package

Package: 3.2 × 5.0 mm, 6-pin surface-mount ceramic package (RoHS-compliant, Pb-free).

Pin/Terminal	Circuit Role	Design Meaning
1	FS (Frequency Select)	Digital control input: FS = 0 selects 100 MHz; FS = 1 selects 212.5 MHz; internally pulled to default state
2	OE (Output Enable)	Active-high enable: OE = 1 enables CLK output; OE = 0 places output in high-impedance state; internal pull-up
3	GND	Electrical and case ground reference - must be connected to system ground plane for noise immunity
4	CLK	CMOS clock output - rail-to-rail swing, 48–52% duty cycle, rise/fall time ≤1.2 ns (15 pF load)
5	NC	No-connect - must remain unconnected; floating or tied to GND may cause malfunction
6	VDD	3.3 V power supply input - bypass capacitor (0.1 µF X7R + 10 µF tantalum) required within 5 mm

Key Features

Feature	Design Value
Dual-frequency selection via single FS pin	Eliminates need for two discrete oscillators or external multiplexing circuitry; reduces BOM count and PCB area
On-chip LDO regulator	Provides >30 dB supply noise rejection up to 1 MHz - simplifies power delivery design in noisy digital systems
Runt suppression on OE and power-on	Prevents false clock edges during power sequencing or OE toggling - critical for deterministic FPGA configuration
Factory-programmed configuration	Delivers fully functional device with zero NRE or lead-time penalty; eliminates post-silicon programming steps

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-frequency XO applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si512CAA000104BAGR	Same Si512 family, 3.2 × 5.0 mm, but configured for 155.52 MHz / 156.25 MHz; uses same CMOS output and ±30 ppm stability	Optimized for SONET/SDH line cards and telecom synchronization; not suitable for PCIe or Ethernet PHY clocking due to frequency mismatch	Select when exact telecom frequencies are required; verify FS polarity and OE configuration match system logic levels
Si542AAB000111DG	Si54x-series ultra-low-jitter XO; single-frequency only (100 MHz); 0.23 ps RMS phase jitter; 2.5 V supply; 2.5 × 3.2 mm package	Lacks dual-frequency capability; targets ultra-low-jitter applications like optical transport where frequency agility is unnecessary	Choose only if single-frequency, sub-0.25 ps jitter is mandatory and board space permits larger decoupling; no FS/OE flexibility

Compared with Si512CAA000104BAGR and Si542AAB000111DG, the 512CAA000210AAG uniquely balances dual-frequency agility, industrial-grade stability, and PCIe/Ethernet-compatible frequencies in a compact 3.2 × 5.0 mm footprint - making it optimal for reconfigurable high-speed interface timing where frequency switching under host control is required.

FAQ

What are the two factory-programmed output frequencies of the 512CAA000210AAG?

The 512CAA000210AAG is factory-configured for 100 MHz and 212.5 MHz. These frequencies are selected via the FS pin: FS = 0 outputs 100 MHz, and FS = 1 outputs 212.5 MHz. Both frequencies meet the ±30 ppm total stability specification and are validated across the full –40 to +85 °C operating range. The 512CAA000210AAG does not support user reprogramming in the field.

Does the 512CAA000210AAG support differential output formats like LVDS or LVPECL?

No, the 512CAA000210AAG is a CMOS-output-only variant. Its part number prefix "512C" indicates CMOS output with OE on pin 2 and 3.3 V supply. Differential formats (LVDS, LVPECL, HCSL) require different ordering codes (e.g., "512B" for LVDS). Attempting to drive differential loads with the 512CAA000210AAG will result in signal integrity degradation and potential timing violations.

What is the function of Pin 5 (NC) on the 512CAA000210AAG, and can it be grounded?

Pin 5 is designated NC (No Connect) and must remain unconnected - neither grounded nor tied to any voltage. Internally, it is not bonded and has no electrical connection. Grounding Pin 5 may introduce parasitic coupling or alter internal impedance matching, potentially affecting startup behavior or jitter performance. The 512CAA000210AAG datasheet explicitly prohibits external connection to this pin.

How does the on-chip LDO in the 512CAA000210AAG improve system-level noise immunity?

The integrated LDO regulator in the 512CAA000210AAG provides >30 dB supply noise rejection up to 1 MHz, attenuating ripple and switching noise from shared digital power rails. This eliminates the need for external ferrite beads or multi-stage RC filters typically required with conventional XOs. As a result, the 512CAA000210AAG maintains sub-0.35 ps RMS phase jitter even when powered from noisy 3.3 V supplies - a key advantage in dense, mixed-signal PCB layouts.

Is the 512CAA000210AAG pin-compatible with other Si512/513 variants in the same package?

Yes - all Si512/513 devices in the 3.2 × 5.0 mm 6-pin package share identical mechanical footprint and pinout mapping. The 512CAA000210AAG (CMOS, OE on pin 2) uses the same pin assignments as Si512 LVDS/LVPECL variants: Pin 1 = FS, Pin 2 = OE, Pin 3 = GND, Pin 4 = CLK/CLK+, Pin 5 = NC/CLK−, Pin 6 = VDD. However, electrical compatibility depends on output format and drive strength - CMOS loads must not be connected to differential receivers.
