Functional description
7.1 PLL clock multiplier
A 6 MHz to 48 MHz clock multiplier Phase-Locked Loop (PLL) is integrated on-chip.
This allows for the use of a low-cost 6 MHz crystal, which also minimizes EMI. No
external components are required for the operation of the PLL.
7.2 Bit clock recovery
The bit clock recovery circuit recovers the clock from the incoming USB data stream
by using a 4 times oversampling principle. It is able to track jitter and frequency drift
as specified in Universal Serial Bus Specification Rev. 2.0.
7.3 Analog transceivers
Two sets of transceivers are embedded in the chip for downstream ports with USB
connector type A. The integrated transceivers are compliant with the Universal Serial
Bus Specification Rev. 2.0 These transceivers interface directly with the USB
connectors and cables through external termination resistors.
7.4 Philips Serial Interface Engine (SIE)
The Philips SIE implements the full USB protocol layer. It is completely hardwired for
speed and needs no firmware intervention. The functions of this block include:
synchronization pattern recognition, parallel to serial conversion, bit (de)stuffing,
CRC checking and generation, Packet IDentifier (PID) verification and generation,
address recognition, and handshake evaluation and generation.

Microprocessor bus interface
8.1 Programmed I/O (PIO) addressing mode
A generic PIO interface is defined for speed and ease-of-use. It also allows direct
interfacing to most microcontrollers. To a microcontroller, the ISP1160 appears as a
memory device with a 16-bit data bus and uses the A0 address line to access internal
control registers and FIFO buffer RAM. Therefore, the ISP1160 occupies only two
I/O ports or two memory locations of a microprocessor. External microprocessors can
read from or write to the ISP1160’s internal control registers and FIFO buffer RAM
through the Programmed I/O (PIO) operating mode.
Figure 3
shows the
Programmed I/O interface between a microprocessor and the ISP1160.
