Description

Frequency Domain Split Band Scrambler

The CMX264 is a frequency domain scrambler for use in analogue cellular phone systems. It contains separate Tx and Rx paths for full duplex operation and operates under µProcessor control via a simple serial interface. In the Tx path, scrambling is achieved by splitting the audio band into two parts, or sub-bands, and frequency inverting each one. The frequency at which the signal is split, the split-point, can be either fixed or rolling between four possible settings resulting in a transmitted audio signal which is unintelligible to eavesdropper.

  • LPC2106BBD48 LQFP40 Microcontroller ARM-core, 64kB RAM, 128k

      LPC2106BBD48 LQFP40 Microcontroller ARM-core, 64kB RAM, 128k
    Single chip microprocessor based on ARM7 core. Key features 16/32 bit ARM7TDMI-S processor. 64 kB on-chip Static RAM. 128 kB on-chip Flash Program Memory. 128 bit wide interface/accelerator enables high speed 60 MHz operation. In-System Programming (ISP) and In-Application Programming (IAP) via on-chip boot-loader software. Flash programming takes 1 ms per 512 byte line. Single sector or full chip erase takes 400 ms. Vectored Interrupt Controller with configurable priorities and vector addresses. EmbeddedICE-RT interface enables breakpoints and watch points. Interrupt service routines can continue to execute whilst the foreground task is debugged with the on-chip RealMonitor software. Embedded Trace Macrocell enables non-intrusive high speed real-time tracing of instruction execution. Multiple serial interfaces including two UARTs (16C550), Fast I²C (400 kbits/s) and SPI. Two 32-bit timers (7 capture/compare channels), PWM unit (6 outputs), Real Time Clock and Watchdog. Up to thirty-two 5 V tolerant general purpose I/O pins in a tiny LQFP48 (7 x 7 mm2) package. 60 MHz maximum CPU clock available from programmable on-chip Phase-Locked Loop with settling time of 100 us. On-chip crystal oscillator with an operating range of 1 MHz to 30 MHz. Two low power modes, Idle and Power-down. Processor wake-up from Power-down mode via external interrupt. Individual enable/disable of peripheral functions for power optimization. Dual power supply: CPU operating voltage range of 1.65 V to 1.95 V (1.8 V +- 8.3 pct.). I/O power supply range of 3.0 V to 3.6 V (3.3 V +- 10 pct.) with 5 V tolerant I/O pads. Mfg: Philips
