The HO732 is a communication interface for Rohde&Schwarz test and measurement equipment. It provides both Ethernet (RJ-45) and USB 2.0 (device, B) connections. The vendor states that the interface can be used with scope/generator/source models in the HM, HMF, HMO, HMP, and HMS series.
Hardware
- ST STM32F407ZGT6 (MCU)
- Altera EPM570F100C5N (MAX II CPLD)
- Micrel KSZ8721BL (10/100 Ethernet PHY)
- SMSC USB3320C (USB PHY)
- (not always populated) CY7C1041DV (SRAM)
- TI LC02A (7402 quad NOR gates? chip select logic? backplane glue?)
The USB interface can be configured to either CDC or TMC.
