Notes
1. PECL outputs (pins DOUT, DOUTQ, ST and STQ) are not connected.
2. Maximum currents are specified at T
3. 2 mV (p-p) single-ended is the minimum input signal to achieve full clipping of the output signal. Typical an input
4. If the input is DC coupled, the preceding amplifier’s output offset voltage should not exceed these limits, in order to
5. Specifications guaranteed by design and characterisation. Each device is tested at full operating speed to guarantee
6.
7. The reference current can be set by connecting a resistor between V
8. R
9. Internal pull-down resistor of 500 k to DGND.
10. Internal series resistor of 1 k .
