Key Features
- 512-Stage Delay Line: Provides a wide range of delay times, suitable for various audio applications.
- Clock Frequency Range: Operates with clock frequencies from 1 kHz to over 2 MHz, allowing for flexible delay time adjustments.
- Integrated Clock Driver: Simplifies external clock sourcing and is TTL/CMOS 5V and 3.3V compatible, eliminating the need for a companion BBD clock IC.
- On-Chip Tetrode Bias Generator: Eliminates the need for externally providing the legacy “14/15 VGG” supply voltage, reducing component count.
- Daisy-Chaining Capability: Allows easy connection of multiple SSI BBD 2100 units for longer delay times without recalibrating inputs and outputs.
- Intermediate Feedback Taps: Access to intermediate feedback taps enables interesting reverb and other psychoacoustic effects.
- Compact Package: Available in an 8-lead SOP surface-mount package, saving board space.
- Single 5V Operation: Simplifies power supply requirements and reduces overall system complexity.
