7.3.14.1 2kHz or 10kHz Selectable Frequency Oscillator

The TPLD1202 has one internal oscillator, selectable to operate at 2kHz or at 10kHz. The user can select one of these operating frequencies for the OSC macro-cell, or the internal oscillator can be bypassed and the operating frequency can come from an external clock.

TPLD1202 Selectable Frequency Oscillator Block Diagram Figure 7-47 Selectable Frequency Oscillator Block Diagram

Following the operating clock input, there are two divider stages that allow users the flexibility of various clock frequencies for use throughout the device.

The first stage divider allows the selection of up to four options from the operating oscillator frequency as listed in Oscillator Pre-dividers. The output of the first divider stage is routed directly to the counter/delay generator macro-cell CLK inputs, where a separate second divider stage is available.

The output of the first divider stage is also routed into a second divider stage within the oscillator macro-cell. The oscillator macro-cell has two separate second stage dividers, allowing for the output of two separate clocks (OUT0 and OUT1) into the connection mux. See Oscillator Output Dividers.
