<Output wave example> 3Gbps PCIExpress compliance pattern

For your reference, 
PCK3GF-1 can be useful as a clock source.
LVC-232C is available as a level converter between RS-232C
such as PC serial port and 3.3V CMOS which is a logic level of APG-3G.
Independent 2 outputs are provided, which can be set different patterns. The setting data can be momorized into the Flash. So when the power is on next time, the stored patterns can be output.

Input clock SMB connector 50 ohm single end AC coupling
Sine wave 30MHz~3000MHz -3dBm~3dBm
Square wave 2KHz~3000MHz -3dBm~3dBm
Shutdown/startup time is within 4nS. Duty ratio 50+/-10%
Trigger input SMB connector 3.3V CMOS 
Pulled up internally at 10K ohm
There is a jitter of +/-5nS up to pattern output start relative to trigger input
Pattern output SMB connector Differential PECL 2 channels
Individual channel patterns can be set. 
Skew between channels is within 20ps
Clock output SMB connector Differential PECL
Skew between patterns is within 100ns
Output bit length 1)External trigger mode
Any bit length in a multiple of 32 of 32bit~256Kbits per 1CH
2)continuous mode
Any bit length in a multiple of an even number of 32bit~256Kbits per 1CH
Trigger mode 1)External trigger mode
2)Continuous mode
