DC2248A-A

LTC6951 Demo Board | 5-Output Integer-N PLL with Integrated VCO, Output Range: 1.95MHz to 2.5GHz (requires DC590 or DC2026)

产品详情

Demonstration circuit 2248A features the LTC6951, an Ultralow Jitter Multi-Output Clock Synthesizer with Integrated VCO.


For ease of use, the DC2248A is powered from a single 6V supply and comes installed with a 100MHz reference. Direct access to the LTC6951 5V, 3.3V and the reference supplies is possible by removing jumpers. For evaluation of the LTC6951 with other references, the DC2248A can be modified to accommodate different onboard or external components.

DC2226A-A

4-Channel 14-Bit 250Msps JESD204B ADC with Clocking [Featuring LTC2123, LTC6951]

产品详情

Demonstration Circuit 2226A-A is a reference design for a four-channel, 250Msps ADC system consisting of two LTC2123, dual 14-bit 250Msps ADCs and a JESD204B Subclass 1 clocking solution based on the LTC6951 Clock Synthesizer with Integrated VCO. Other dash options reserved for future use. No external clock source is required to operate the board; however, the on-board 100MHz reference oscillator may be bypassed, allowing synchronization to other equipment.
