TDA8044

INTEGRATED CIRCUITS DATA SHEET TDA8044 Satellite demodulator and decoder Product specification Supersedes data of 1998 Nov 17 File under Integrated Circuits, IC02 2000 Feb 21 Philips Semiconductors Product specification Satellite demodulator and decoder FEATURES General features: – One-chip Digital Video Broadcasting (DVB) compliant Quadrature Phase Shift Keying (QPSK) and Binary Phase Shift Keying (BPSK) demodulator and concatenated Viterbi/Reed-Solomon decoder with de-interleaver and de-randomizer (ETS 300 421) – 3.3 V supply voltage (input pads are 5 V tolerant) – Standby mode for low power dissipation – Internal clock PLL to allow low frequency crystal application and selectable clock frequencies – Power-on reset module – Package: QFP100 – Boundary scan test. QPSK/BPSK demodulator: – Interpolator and anti-alias filter to handle a large range of symbol rates without additional external filtering – On-chip AGC of the analog input I and Q baseband signals or tuner AGC control – Two on-chip matched Analog-to-Digital Converters (ADCs; 7 bits) – Half Nyquist (square root raised-cosine) filter with selectable roll-off factor – Large range of symbol frequencies: 0.5 to 45 Msymbols/s for TDA8044 and 0.5 to 30 Msymbols/s for TDA8044A, including Single Carrier Per Channel (SCPC) function – Can be used at low channel Signal-to-Noise ratio (S/N) – Internal carrier recovery, clock recovery and AGC loops with programmable loop filters – Two loop carrier recovery enabling phase tr...
