Sinara 8452 DSP "Stabilizer"
The Sinara 8452 DSP is a CPU-based dual-channel digital signal processing platform, particularly suited to servo applications. It can be controlled by Kasli or work standalone with Power-over-Ethernet (PoE) supply. Features include:
- 400MHz STM32H743ZIT6
- dual 16bit ADC with x2, x5, x10 PGA (2MS/s)
- 16bit AD5542A DAC (1µs settling time)
- PoE supply
- 10/100Base-T Ethernet
- Sinara-compatible EEM port
- Connectors for optional analog front-end (AFE) module
- IDC connectors for BNC-IDC/SMA-IDC extension for digital IO and aux analog inputs and outputs
The 8452 DSP Stabilizer can be used as a general-purpose PID controller or combined with 4459 Pounder (see below) as a Pound-Drever-Hall lock generator. Several additional AFE extensions are under development, including a high-current power supply for magnets.
The standard open source firmware that comes with the board has the following features:
- dual channel
- SPI ADC
- SPI DAC
- fixed AFE gains
- 500 kHz rate, timed
- < 2 µs latency, unmatched
- f32 IIR math
- generic biquad (second order) IIR filter
- anti-windup
- derivative kick avoidance
- configurable output limits
To purchase this controller, email sales@m-labs-intl.com. We also offer firmware customizations and development of new features. Note that features that are not implemented in the open source code above (e.g. control from Kasli) are not supported unless purchased separately.
Sinara 4459 PDH Lock Generator "Pounder"
The Sinara 4459 Pounder, a dual-channel Pound-Drever-Hall (PDH) lock generator mezzanine for the 8452 DSP Stabilizer, is currently available from M-Labs and can be purchased together with Stabilizer or separately. 4459 Pounder is based on the 4-channel AD9959 DDS (500MSPS, 10bit) and is designed to operate at 1 - 200MHz. Support is integrated into the main Stabilizer firmware.
Sinara 8462 Fast DSP "Fast Servo"
The Sinara 8462 DSP Fast Servo is a dual-channel digital signal processing platform and high-speed servo, closely related to the 8452 DSP Stabilizer but offering a significant performance advantage (higher speed, lower latency). It uses the same form factor and I/O as 8452 Stabilizer and can work standalone with DC or Power-over-Ethernet (PoE) supply. Features include:
- Trenz TE0715-04 SoC module
- dual 125MHz 16bit ADC
- dual 125MHz 14bit DAC
- PoE supply
- 100Base-T Ethernet
- Sinara-compatible EEM port
- Connectors for optional analog front-end (AFE) module
- MicroUSB interface
