Notes

1. These values are specified for a symbol rate of 27.5 Msymbols/s, a puncturing rate of 3⁄4 and a clock frequency of

65 MHz.

2. A range from 3 to 32 Msymbols/s can be achieved with one SAW filter. By using an internal clock divider and

reducing the external SAW filter bandwidth, symbol rates down to 0.5 Msymbols/s can be achieved by using a

65 MHz crystal clock.

3. This data was measured in a laboratory environment at a symbol rate of 27.5 Msymbols/s, a clock frequency of

65 MHz, a signal-to-noise ratio of 4.5 dB and including a tuner.
