ISP1504A1; ISP1504C1

ULPI HS USB OTG transceiver

• Differential and single-ended receivers to receive data at high-speed, full-speed and

low-speed

• Squelch circuit to detect high-speed bus activity

• High-speed disconnect detector

• 45

Ω high-speed bus terminations on DP and DM

• 1.5 k

Ω pull-up resistor on DP

• 15 k

Ω pull-down resistor on DP and DM

For details on controlling resistor settings, see Table 8.

7.4 Voltage regulator

The ISP1504x1 contains a built-in voltage regulator that conditions the VCC supply for use

inside the ISP1504x1. The voltage regulator:

• Supports input supply range of 3.0 V < VCC < 4.5 V

• Can be supplied from a battery with a voltage range of 3.0 V to 4.5 V

• Supplies internal circuitry with 1.8 V and 3.3 V

• Automatically bypasses the internal 3.3 V regulator when VCC < 3.5 V, drawing power

directly from the VCC pin

To save current, the voltage regulator will be shut down, if VCC(I/O) is not present or if

pin CS_N/PWRDN is at a HIGH level.

Remark: The REG1V8 and REG3V3 pins require an external 0.1

µF capacitor in parallel

with a 4.7

µF capacitor. For details, see Section 15.

7.5 Crystal oscillator and PLL

The ISP1504x1 has a built-in crystal oscillator and a Phase-Locked Loop (PLL) for clock

generation.

The crystal oscillator takes a sine-wave input from an external crystal, on the XTAL1 pin,

and converts it to a square wave clock for internal use. Alternatively, a square wave clock

of the same frequency can also be directly driven into the XTAL1 pin. Using an existing

square wave clock can save the cost of the crystal and also reduce the board size. The

input clock or crystal frequency supported is 19.2 MHz or 26 MHz.

The PLL produces the following frequencies, irrespective of the clock source:

• 60 MHz clock for the ULPI interface controller

• 1.5 MHz for the low-speed USB data

• 12 MHz for the full-speed USB data

• 480 MHz for the high-speed USB data

• Other internal frequencies for data conversion and data recovery

7.6 OTG module

This module contains several sub-blocks that provide all the functionality required by the

USB OTG speciﬁcation. Speciﬁcally, it provides the following circuits:
