CMX994EQ4 Product Details

The CMX994EQ4 is a multi-mode wireless data modem and quadrature modulator with integrated VCO designed by CML Microcircuits. Part of the CMX994 family, it features a wide operating frequency range of 100 MHz to 1 GHz, supporting modulation schemes like GMSK, QPSK, and 16/64-QAM, making it ideal for satellite communications, point-to-point radio links, IoT devices, and various wireless standards including Bluetooth, Zigbee, Wi-Fi, and LTE. Housed in a 40-terminal HVQCCN (Quad Flat No-Lead) package (6x6mm, 0.5mm pitch), it operates at a nominal 3.3V supply voltage, offers low power consumption, high linearity, and includes a high-performance DSP core with flexible interfaces (SPI, UART, I2C) for seamless integration with external components.

Benefits

Multi-mode wireless data modem with integrated quadrature modulator and VCO for compact transceiver designs
Wide 100 MHz to 1 GHz frequency range enabling compatibility with diverse wireless standards
Integrated PLL with 1 Hz frequency resolution for precise frequency tuning
Supports multiple modulation schemes (GMSK, QPSK, 16/64-QAM, AM/FM/PM) for flexible protocol adaptation
Low power consumption suitable for battery-operated IoT and portable devices
High linearity and phase accuracy ensuring reliable signal transmission in challenging RF environments
High-performance DSP core for advanced signal processing capabilities
Flexible SPI, UART, and I2C interfaces for easy integration with microcontrollers and RF front-ends

Pinout

The CMX994EQ4 features a 40-terminal HVQCCN (Quad Flat No-Lead) package with a 6mm x 6mm footprint and 0.5mm terminal pitch. Key functional pins include power supply, ground, RF interfaces, control signals, and communication ports for external device integration.

VDD: Nominal 3.3V supply voltage input
GND: Ground reference for all internal circuits
RF_OUT: Quadrature modulated RF output signal
I_IN / Q_IN: In-phase (I) and Quadrature (Q) baseband input signals
SPI_SCLK / SPI_MOSI / SPI_MISO / SPI_CS: Serial Peripheral Interface pins for device control and data transfer
UART_TX / UART_RX: Universal Asynchronous Receiver/Transmitter pins for serial communication
I2C_SDA / I2C_SCL: I2C interface pins for configuration and control
PLL_REF: Reference clock input for the integrated phase-locked loop
MODE_SEL: Modulation mode selection pin to switch between supported schemes

The quad-terminal layout facilitates compact surface-mount integration, with dedicated pins for core functions ensuring efficient signal routing and minimal interference.
