BIAS PIN OPERATION
The Bias Select Pin (BIAS) gives the user, who is able to operate
the AD9260 at a slower clock rate, the added flexibility of
running the device in a lower, power consumption mode when
it is clocked at less than 20 MHz.
This is accomplished by scaling the bias current of the AD9260
as illustrated in Figure 69. The bias amplifier drives a source
follower and forces 1 V across REXT, which sets the bias current.
This effectively adjusts the bias current in the modulator
amplifiers and FLASH preamplifiers. When a large value of REXT
is used, a smaller bias current is available to the internal
amplifier circuitry. As a result these amplifiers need more time
to settle, thus dictating the use of a slower clock as the power
is reduced. Refer to the characterization curves shown in Figure
47 to Figure 54 revealing the performance tradeoffs.
The scaling is accomplished by properly attaching an external
resistor to the BIAS pin of the AD9260 as shown in Table 17.
REXT is normally 2 k for a clock speed of 20 MHz and scales
inversely with clock rate. Because BIAS is an external pin,
minimization of capacitance to this pin is recommended in
order to prevent instability of the bias pin amplifier.
