VP310 - Key Features
Conforms to EBU specification for DVB-S and DirecTV specification for DSS.
On-chip digital filtering supports 1 to 45MBaud Symbol rates.
On-chip 6-bit 60 or 90MHz dual-ADC.
High speed scanning mode for blind symbol rate and code rate acquisition.
Up to ± 15MHz LNB frequency tracking.
Fully digital timing and phase recovery loops.
High level software interface for minimum development time.
DiSEqC v1.1: control outputs for full control of LNB and dish.
Applications
DVB 1 to 45MBaud compliant satellite receivers.
DSS 20MBaud compliant satellite receivers.
SCPC receivers. (Single Channel Per Carrier)
SMATV trans-modulators. (Single Master Antenna TV)
LMDS. (Local Multipoint Distribution Service)
Satellite PC applications.
The VP310 is a QPSK/BPSK 1 to 45MBaud demodulator and channel decoder for
digital satellite television transmissions to the European Broadcast Union ETS 300 421
specification. It receives analog I and Q signals from the tuner, digitises and digitally
demodulates this signal, and implements the complete DVB/DSS FEC (Forward Error
Correction), and de-scrambling function. The output is in the form of MPEG2 or DSS
transport stream data packets. The VP310 also provides automatic gain control to the
RF front-end devices.
The VP310 has a serial I2C port interface to the control microprocessor. Minimal
software is required to control the VP310 because of the built in automatic search and
decode control functions.
