For detailed specifications, please refer to the COMBGEN6GDIFF Manual.
- Differential output - can also provide two separate single ended complementary outputs.
- Pulse height of up to +4V peak into 50 ohms, on positive output
- Pulse height of up to -4V peak into 50 ohms, on negative output
- Rise time < 80pS, FWHM of approximately 120pS
- Produces pulse on both edges of input clock, thereby doubling frequency.
- Input clock may be sinewave from 50MHz to 2GHz or square wave from 5MHz to 2GHz, producing fundamental comb tooth energy from 10MHz to 4GHz.
- Usable energy to >10GHz.
- Can drive any load, including short, without damage.
- Power Requirements: -12V @ 120mA and +24V @ 80mA
Output Comb Spectrum on + output, shown from DC to 10 GHz, for 200MHz clock input. Output spectrum consists of even harmonics (e.g. 400MHz, 800MHz ... 9.6GHz, 10GHz). -3dB point is approximately 3GHz. Odd harmonics (e.g. 100MHz, 300MHz are suppressed by approximately 30dB at low frequencies (to 1.2GHz), and are supressed by approximately 20dB up to 2.8GHz, degrading to 10dB at >8GHz.
Pulse train produced when comb COMBGEN6DIFF is driven by a 200 MHz input clock, resulting in 400 MPPS.
