All differential inputs and six of the differential outputs are populated with 0.5" spaced SMA connectors. These outputs are AC-coupled with 50Ω transmission lines making them suitable to drive 50Ω impedance instruments. The remaining five differential outputs are terminated with 100Ω.
The LTC6952's EZSync™ and SYSREF request functions are made available via the LTC6952 SPI interface or the EZS_SRQ SMA/turret connectors. The SMA placement was designed for ease of connection for all multi-part synchronization and SYSREF request modes.
The VTUNE and VCO SMAs can mate directly with the DC2664A VCO rider board. This options allows for a quick method to evaluate multiple voltage-controlled oscillators.
A DC2026 USB Serial Controller Bboard is used for SPI communication with the LTC6952, controlled by the supplied LTC6952Wizard™ software.
