ISP1501 is a USB peripheral high-speed transceiver chip of ISP company, which supports USB2.0 standard, has parallel to serial converter and serial to parallel converter, supports 12MHz crystal, has 3.3V and 5V digital input interface
The ISP1501 is a full‑function Hi‑Speed USB peripheral transceiver designed to provide an analog front‑end for ASICs and FPGAs. It supports both full‑speed and high‑speed USB physical layers and requires only a minimal number of external components.
The document includes features such as integrated PLL, separate analog/digital supplies, a 16‑bit bi‑directional data bus, and extensive pin‑out information. Applications listed include scanners, digital cameras, printers, and external storage devices. Ordering information, pinning diagrams, and functional descriptions are provided for designers and service technicians.
| Operating temperature range | -40 °C to +85 °C |
|---|---|
| Package | LQFP48, 48 leads |
| PLL oscillator | 12 MHz crystal, internal 480 MHz clock |
| Derived clock outputs | 30 MHz (CLKOUT30) and 48 MHz (CLKOUT48) |
| Analog and digital supplies | Separate 3.3 V supplies |
| Digital input tolerance | 3.3 V or 5 V tolerant |
