OPERATION
POWER, GROUND AND EXTERNAL COMPONENTS
Figure 18 shows the recommended power and ground connection method for the DS3F device. Separate
planes should be employed for VDD and GND. Bypass networks consist of a 10 F capacitor in parallel with
0.1 F capacitors for each VDD pin, as shown. These 0.1 F capacitors should be RF-quality and closely con-
nected to each of the device’s VDD pins to decouple them to ground.
THROUGHPUT DELAYS
The DS3F throughput delays for the serial terminal interface are given below in terms of DS3 bit times
(1 bit = 22.35 nsec nominal):
1. The throughput delay from the transmit terminal side input to the transmit line side output is 3 bit
2. The throughput delay from the receive line side input to the receive terminal side output is 2 bit times.
