QUICK REFERENCE DATA

Notes

1. Typical value is specified for a symbol rate of 27.5 Msymbols/s, a puncture rate of 3

⁄4 and a supply voltage of 3.3 V.

Maximum value is specified for a symbol rate of 30 Msymbols/s, a puncture rate of 7

⁄8, a supply voltage of 3.6 V and

using a 4 MHz crystal.

2. Implementation loss at the demodulator output and minimum SNR to lock the TDA8083 are measured including tuner

in a laboratory environment at a symbol rate of 27.5 MS/s.
