DESCRIPTION
Designed for World Space satellites digital audio receivers, the STA002 Digital Receiver Front-end integrates all the blocks needed to demodulate incoming digital satellite audio signals from the tuner: analog to digital converter, QPSK demodulator, signal power estimator, automatic gain control, Viterbi decoder, deinterleaver, Reed-Solomon decoder and energy dispersal descrabler. Its advanced error correction functions guarantees a low error rate even with small low gain receiver antennas.
FRONT_END INTERFACE:
■ IF input carrier frequency: f = 1.84 MHz
■ Single internal 6 bit A/D converter
■ QPSK demodulation
■ Input symbol frequency: Fs = 1.84 Msymbols/s
■ Digital Nyquist root filter:
- roll-off value of 0.4
■ Digital carrier loop:
- on-chip quadrature demodulator and tracking loop
- lock detector
- C/N indicator
■ Digital timing recovery:
- internal timing error evaluation, filter and correction
■ Digital AGC:
- internal signal power estimation and filter
- output control signal for AGC (1 bit PWM)
BACK_END INTERFACE:
■ Broadcast Channel selection
■ Audio Service Component selection to MPEG decoder
■ Service Component selection
CONTROL:
■ I2C serial Bus control interface
DECRYPTION:
■ WES scheme supported
