Product details

Overview

DS4000A0/WBGA from Maxim Integrated is a digitally controlled temperature-compensated crystal oscillator (DC-TCXO) with dual CMOS square-wave outputs: fixed-frequency F1 at 10.00000 MHz and programmable F2 derived via integer division of F1, operating over 0°C to +70°C in a 24-pin WBGA package. It integrates a 10-bit digital temperature sensor (±3°C accuracy), 2-wire serial interface (up to 400 kHz), and ±10 ppm digital frequency tuning capability for precision timing in PLL reference and wireless infrastructure applications.

For engineers reviewing the DS4000A0/WBGA datasheet, DS4000A0/WBGA pinout, DS4000A0/WBGA application, or DS4000A0/WBGA equivalent, this page delivers verified specifications including F1/F2 output behavior, TCXO stability (±1.0 ppm over temperature), 2-wire timing compliance, thermal sensor resolution (+0.25°C), and WBGA package mapping - all critical for clock tree validation, frequency agility design, and industrial-grade timing system integration.

Technical Context

The DS4000A0/WBGA implements a digitally tuned analog TCXO core, where factory-compensated crystal loading is adjusted in real time using two's complement frequency offset values (±10.16 ppm range, 0.08 ppm/LSB) written to register 66h via I²C. Its dual-output architecture separates fixed reference (F1) from programmable division (F2), with F2 configurable as either n+1 or 2(n+1) division of F1 via the duty cycle bit in control register 60h.

Temperature sensing operates autonomously in background mode, storing completed 10-bit conversions in registers 64h/65h for master readout; conversion time is 250–300 ms. The 2-wire interface supports both standard (100 kHz) and fast mode (400 kHz), with open-drain SDA/SCL requiring external pullups and slave address selection via A0 pin (100010A0 binary).

Pin/Terminal	Circuit Role	Design Meaning
1A, 1B, 1C, 1D, 2C, 2D	GND	Dedicated digital ground connections - must be tied to low-impedance system ground plane to suppress digital switching noise.
2A, 2B	N.C.	No internal connection - leave unconnected; no grounding or routing required.
3A, 3B	GNDOSC	Oscillator-specific ground - isolate from digital GND to prevent noise injection into sensitive crystal circuitry.
3C, 3D	VOSC	Dedicated oscillator power supply - decouple locally with 100 nF ceramic capacitor to maintain clean 5 V for crystal bias.
4A, 4B	A0	Slave address LSB - hardwired HIGH or LOW to select I²C address (1000100x or 1000101x), enabling dual-device bus sharing.
4C, 4D	F1	Fixed-frequency CMOS output - provides 10.00000 MHz reference with 40–60% duty cycle; drive capability limited to 10 pF load.
5A, 5B	SDA	Open-drain bidirectional data line - requires external pullup resistor (typically 2.2–4.7 kΩ) to VCC for I²C communication.
5C, 5D	VCC	Digital supply input - powers logic, interface, and sensor blocks; bypass with 100 nF ceramic capacitor near package.
6A, 6B	SCL	Open-drain clock input - synchronized to master-generated clock; pullup resistor required for proper edge timing.
6C, 6D	F2	Programmable CMOS output - frequency set by FSR register (5Dh); supports integer division of F1 with selectable 50% duty cycle (DC bit).

Key Features

Feature	Design Value
Dual independent outputs	F1 provides stable 10 MHz reference; F2 offers flexible division-based frequencies (e.g., 5 MHz, 3.33 MHz) without external dividers.
On-chip 10-bit temperature sensor	Delivers die temperature readings every 250–300 ms with ±3°C accuracy - enables closed-loop thermal compensation in GPS receivers.
±10 ppm digital frequency tuning	Allows microcontroller-driven calibration of aging or board-level thermal gradients via I²C, reducing need for manual trim capacitors.
Separate oscillator power/ground	VOSC/GNDOSC isolation prevents digital supply noise from modulating crystal frequency - critical for phase noise performance in telecom radios.
I²C-compatible 2-wire interface	Supports both 100 kHz and 400 kHz modes with standard protocol - simplifies integration into existing MCU-based timing management firmware stacks.

FAQ

What is the base frequency of the DS4000A0/WBGA?

The DS4000A0/WBGA has a fixed base frequency of 10.00000 MHz on its F1 output, as indicated by the top marking "DS4000A0" and confirmed in the Selector Guide. This frequency is factory-trimmed and serves as the reference for both the stable output and the programmable F2 divider chain. The DS4000A0/WBGA does not support user-reprogrammable base frequencies - only F2 output frequency can be altered via the FSR register.

Does the DS4000A0/WBGA include an integrated temperature sensor?

Yes, the DS4000A0/WBGA integrates a factory-calibrated 10-bit digital temperature sensor with ±3°C accuracy and +0.25°C resolution. Temperature data is stored in registers 64h/65h and accessible via the 2-wire interface using the READ TEMPERATURE command (0x64). The DS4000A0/WBGA performs continuous background conversions every 250–300 ms, enabling real-time thermal monitoring without host intervention.

How is the F2 output frequency programmed on the DS4000A0/WBGA?

The F2 output frequency on the DS4000A0/WBGA is set by writing an 8-bit value to the Frequency Select Register (FSR) at address 5Dh. With the Duty Cycle (DC) bit = 0, F2 = F1 / (FSR + 1); with DC = 1, F2 = F1 / [2 × (FSR + 1)]. For example, writing 0x09 to FSR yields F2 = 10 MHz / 10 = 1 MHz (DC=0) or 500 kHz (DC=1). The DS4000A0/WBGA requires TCXO Control Register (60h) bit F2OE = 1 to enable the output.

What is the function of the A0 pin on the DS4000A0/WBGA?

The A0 pin on the DS4000A0/WBGA sets the LSB of the 7-bit I²C slave address, allowing two DS4000A0/WBGA devices to share the same 2-wire bus. When A0 is pulled HIGH, the address becomes 1000101x; when pulled LOW, it becomes 1000100x (where x = R/W bit). This hardware-selectable addressing eliminates software address conflicts in multi-oscillator timing systems and is documented in the SLAVE ADDRESS section of the DS4000A0/WBGA datasheet.

What package type and dimensions does the DS4000A0/WBGA use?

The DS4000A0/WBGA uses a 24-ball wafer-level BGA (WBGA) package with 0.85 mm ball pitch, overall footprint of 3.54 mm × 3.54 mm, and solder-mask-defined pads per drawing 56-G6022-001A (variation V24-1). This package is distinct from standard plastic BGAs - it features wafer-level packaging for reduced height and improved thermal performance. The DS4000A0/WBGA is not RoHS/lead-free compliant per Maxim's materials analysis.
