Description
AT48802 .
The AT48802 Spread-Spectrum Signal Processor (SSSP) chip from Atmel handles all PN code generation, synchronization, and handshaking required for eith.
Features
* Two Independent PN (Pseudo-Random Noise) Generators Programmable R7 (128) to R13 (8,192) PN Sequence Lengths Programmable Tau-Dither Amplitude Programmable PN Phase Adjustment to 1/16 Chip Correlation Acquisi
Applications
* it is necessary to power down one end of the communication link except when a call is to be made. The sleep mode circuits of the AT48802 control this function. The sleep mode circuits consist of a timer which runs from a low frequency (4 kHz) RC oscillator and a set of latches to interact with the r
