UWB transmitter for intrachip connection

hi
i m designing a transmitter of 5Ghz uwb transmitter for intrachip connection.my data rate entering into the transmitter is 5Gbps.i want to ask that what can be the minimum frequency of the clock that is generating this data in the chip?is it 5 Ghz too or lower or different?

please help me,please

What is your modulation?
Such as you use 128QAM, that is 7bps/Hz, so your clock should be 5Gbps/7bps/Hz=0.7143GHz.

hi,
my modulation technique is BPSk.transmitter has a clock of 5 GHz.data enters at a rate of 5Gbps and transmitted also in 5 gbps by bpsk technique.what can be the operating frequency of a chip that can generate 5 gbps data

For BPSK, the spectrum effieciency is 1bps/Hz, so your clock shoud be 5G. As you already have 5G clock, so ues it.
