RESET
I/TTL
System reset. The RESET input is low active. In order to ensure
correct operation a "Power On Reset"
must be performed. The
RESET pulse must have a minimum duration of two clock periods
of the system clock CLK1.

14.7.LM317T
14.7.1.Description
The LM317T is an adjustable 3 terminal positive voltage regulator capable of supplying in excess of 1.5
amps over an output range of 1.25 to 37 volts. This voltage regulator is exceptionally easy to use and
requires only two external resistors to set the output voltage. Further, it employs internal current limiting,
thermal shutdown and safe area compensation, making it essentially blow–out proof. The LM317
serves a wide variety of applications including local, on card regulation. This device can also be used to
make a programmable output regulator, or by connecting a fixed resistor between the adjustment and
output, the LM317 can be used as a precision current regulator.
14.7.2.Features
• Output Current in Excess of 1.5 A
• Output Adjustable between 1.2 V and 37 V
• Internal Thermal Overload Protection
• Internal Short Circuit Current Limiting Constant with Temperature
• Output Transistor Safe–Area Compensation
• Floating Operation for High Voltage Applications
• Available in Surface Mount D
2
PAK, and Standard 3–Lead Transistor Package
• Eliminates Stocking many Fixed Voltages
14.8.DDP3310
14.8.1.Description
The DDP 3310B is a single-chip digital Display and Deflection Processor designed for high-quality
back-end applications in 100/120-Hz TV sets with 4:3 or 16:9 picture tubes. The IC can be combined
with members of the DIGIT 3000 IC family (VPC 32xx, TPU 3040), or it can be used with third-party
products. The IC contains the entire digital video component and deflection processing and all analog
interface components.
14.8.2.Features
Video processing
– linear horizontal scaling (0.25 … 4)
– non-linear horizontal scaling “panorama-vision”
– dynamic peaking
