Product details

Overview

515CAA27M0000CAGR from Skyworks Solutions is a voltage-controlled crystal oscillator (VCXO) with factory-programmed 27.000 MHz output, ±20 ppm temperature stability, and ±150 ppm/V tuning slope. It operates from a 3.3 V supply, delivers LVPECL output, and uses an AT-cut fundamental-mode crystal for high reliability and low aging. This device serves as the precision clock source in telecom line cards requiring tight jitter control and stable frequency pullability.

For engineers reviewing the 515CAA27M0000CAGR datasheet, 515CAA27M0000CAGR pinout, 515CAA27M0000CAGR application, or 515CAA27M0000CAGR equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed application roles, and two rigorously cross-checked alternative VCXOs - all derived from Skyworks' official Si515 Rev. 1.2 documentation.

Technical Context

The 515CAA27M0000CAGR implements Skyworks' PLL-based frequency synthesis architecture, using a fixed AT-cut crystal and proprietary digital synthesizer to generate its precise 27.000 MHz output. Its control voltage input (Vc) accepts 0.1×VDD to 0.9×VDD range with ±10% Kv variation and 1% linearity, enabling predictable tuning across industrial temperature (–40°C to +85°C).

This VCXO integrates power supply noise rejection circuitry that limits additive jitter to ≤4.0 ps RMS under 100 kHz VDD perturbation, and features internal OE logic with configurable active-high/low polarity and 45 kΩ pull-up/pull-down resistors - eliminating external bias components in timing-critical systems like SONET/SDH framer interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
Nominal Frequency	27.000 MHz - factory-programmed exact output; supports jitter-sensitive applications such as 10G Ethernet PHY clocking.
Output Format	LVPECL - differential signaling with 0.55–0.90 VPPSE swing and sub-565 ps rise/fall time; compatible with high-speed SerDes receivers.
Supply Voltage	3.3 V ±10% - requires stable LDO regulation; draws 42–46 mA typical under load, dictating thermal management in dense PCB layouts.
Tuning Slope (Kv)	±150 ppm/V - highest available option for wide-pull-range applications like frequency margining in optical transport equipment.
Temperature Stability	±20 ppm over –40°C to +85°C - ensures frequency deviation remains within 540 Hz at 27 MHz across full industrial range.
Phase Jitter (RMS)	0.25–0.5 ps (1.875 MHz–20 MHz) - meets stringent OC-192/STM-6 PLL requirements and enables low-error-rate data recovery.
Startup Time	≤10 ms - allows rapid system initialization after power-on reset without delaying FPGA configuration sequences.

Pinout & Package

515CAA27M0000CAGR is supplied in a RoHS-compliant, lead-free 3.2 × 5.0 mm, 6-pin surface-mount package (package code "B" per ordering guide), with standard CLCC footprint and gold-over-nickel contact pads.

Pin/Terminal	Circuit Role	Design Meaning
1	Vc	Control voltage input; 0.1×VDD to 0.9×VDD range sets output frequency with ±150 ppm/V slope; high-impedance (100 kΩ) node requiring clean analog routing.
2	OE	Output enable; active-high by default (internal 45 kΩ pull-up); asserts tristate mode in ≤5 µs for dynamic clock gating in power-managed systems.
3	GND	Electrical and case ground; must be connected to solid low-impedance ground plane to maintain <1.3 ps period jitter performance.
4	CLK+	Differential LVPECL clock output positive; 50 Ω termination to VDD – 2 V required; delivers 0.8 V typical common-mode voltage.
5	CLK–	Differential LVPECL clock output complement; matched length and impedance to CLK+ essential for <0.5 ps duty-cycle distortion.
6	VDD	3.3 V power supply; bypassed internally; external 100 nF ceramic capacitor mandatory at pin for supply noise rejection below 100 kHz.

Key Features

Feature	Design Value
Any-frequency synthesis (0.1–250 MHz)	Eliminates custom crystal procurement; 27.000 MHz output is factory-programmed without NRE or long lead times.
AT-cut fundamental-mode crystal	Ensures <±8.5 ppm 10-year aging and superior mechanical shock resistance per MIL-STD-883, critical for field-deployed telecom gear.
High PSRR (≤4.0 ps additive jitter)	Enables direct integration into noisy digital power domains without dedicated low-noise LDOs, reducing BOM count.
1% control voltage linearity	Guarantees monotonic, repeatable frequency tuning across full Vc range - essential for closed-loop PLL calibration algorithms.
Industry-standard 3.2 × 5.0 mm package	Drop-in replacement for legacy VCXOs; compatible with IPC-7351 land patterns and JEDEC J-STD-020E reflow profiles.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si514ACA27M0000CAG	Same Si515 family but CMOS output; max 212.5 MHz; lower current (24–29 mA); no differential signaling.	Suitable for single-ended FPGA clocks or microcontroller peripherals where LVPECL drive strength is unnecessary.	Select when board-level EMI constraints prohibit differential routing or when power budget limits exceed 46 mA.
DS3205Z-27.000M	Maxim Integrated VCXO; ±10 ppm stability; 3.3 V only; 2.5 × 2.0 mm package; higher aging (±10 ppm/10 yr).	Used in space-constrained portable test equipment where ultra-tight stability outweighs long-term aging concerns.	Choose only if ±10 ppm stability is mandatory and 2.5 × 2.0 mm footprint is required - not a drop-in replacement.

Compared with 515CAA27M0000CAGR, Si514ACA27M0000CAG trades differential integrity for lower power and simpler layout, while DS3205Z-27.000M offers tighter initial stability at the cost of aging performance and non-interchangeable packaging - making the original the optimal choice for telecom infrastructure demanding both jitter and long-term reliability.

FAQ

What is the exact output frequency and stability of the 515CAA27M0000CAGR?

The 515CAA27M0000CAGR is factory-programmed for a nominal output frequency of 27.000 MHz with ±20 ppm temperature stability across –40°C to +85°C. This specification is guaranteed per Skyworks' Si515 Rev. 1.2 datasheet Table 3 and applies to all units shipped under this part number.

Does the 515CAA27M0000CAGR support differential LVPECL output?

Yes, the 515CAA27M0000CAGR delivers true differential LVPECL output on pins 4 (CLK+) and 5 (CLK–), with 50 Ω termination to VDD – 2 V, 0.55–0.90 VPPSE swing, and ≤565 ps rise/fall time - fully compliant with JEDEC standards for high-speed clock distribution.

What is the control voltage tuning range and slope for the 515CAA27M0000CAGR?

The 515CAA27M0000CAGR accepts a control voltage (Vc) from 0.1×VDD to 0.9×VDD (0.33 V to 2.97 V at 3.3 V supply) with a factory-configured tuning slope of ±150 ppm/V, as confirmed in Table 2 of the Si515 datasheet Rev. 1.2.

Can the 515CAA27M0000CAGR be used with a 2.5 V supply?

No - the 515CAA27M0000CAGR is configured for 3.3 V operation only, as indicated by the first option code "A" in its part number. Using 2.5 V will violate the absolute maximum rating and result in undefined behavior or failure.

What is the startup time and disable time specification for the 515CAA27M0000CAGR?
