Description
 The GS1582 is the next generation multi-standard serializer with an integrated cable driver.
The device provides robust parallel to serial conversion, generating a SMPTE 292M/259M-C compliant serial digital output signal.
The integrated cable driver features an output disable (high impedance) mode and an adjustable signal swing.
Data input is accepted in 20-bit parallel format or 10-bit parallel format. An associated parallel clock input must be provided at the appropriate operating frequency; 74.25/74.1758/13.5MHz (20-bit mode) or 148.5/148.352/27MHz (10-bit mode).
The GS1582 features an internal PLL which, if desired, can be configured for a loop bandwidth below 100kHz.
When used in conjunction with the GO1555 Voltage Controlled Oscillator, the GS1582 can tolerate well in excess of 300ps jitter on the input PCLK and still provide output jitter within SMPTE specifications.
In addition to serializing the input, the GS1582 performs NRZ-to-NRZI encoding and scrambling as per SMPTE 292M/259M-C when operating in SMPTE mode.
When operating in DVB-ASI mode, the device will insert K28.5 sync characters and 8b/10b encode the data prior to serialization.
The device also provides a range of other data processing functions.
All processing features are optional and may be enabled/disabled via external control pin(s) and/or host interface programming.
The GS1582 can embed up to 8 channels of audio into the video data stream in accordance with SMPTE 299M and SMPTE 272M.
The audio input signal formats supported by the device include AES/EBU and I2S serial digital formats with a 16, 20 or 24 bit sample size and a 48 kHz sample rate.
Additional audio processing features include individual channel enable, channel swap, group swap, ECC generation and audio channel status insertion.
Typical power consumption, including the GO1555 VCO, is 500mW.
The standby feature allows the power to be reduced to 125mW.
Power may be reduced to less than 10mW by also removing the power to the cable driver and eliminating transitions at the parallel data and clock inputs.
The GS1582 is Pb-free and RoHS compliant.

 Combining logic and power, the UDN2936W-120 provides commutation and drive for three-phase brushless dc motors.
Each of the three outputs are rated at 45 V and ±2 A (±3 A peak), and include internal ground clamp and flyback diodes.
The driver also features internal commutation logic, PWM current control, and thermal shutdown
protection.

The commutating logic is programmed for 120° electrical separation.
The UDN2936W-120 can replace the original UDN2936W (60° electrical separation) by simply adding an inverter at the H2 input.
Current control is accomplished by sensing current through an external sense resistor and pulse-width modulating the source drivers.
Voltage thresholds and hysteresis can be externally set by the user.
If desired, internal threshold and hysteresis defaults (300 mV, 7.5 percent) can be used.
The UDN2936W-120 also includes braking and direction control.
Internal protection circuitry prevents crossover current when braking or changing direction.
The UDN2936W-120 is also available for operation between -40°C and +85°C.
To order, change the prefix from ‘UDN’ to ‘UDQ’.
For maximum power-handling capability, the UDN2936W-120 is supplied in 12-pin single in-line power-tab package.
An external heat sink may be required for high-current applications.
The tab is at ground potential and needs no insulation.

DESCRIPTION
 The UPD16803 is a monolithic dual H bridge driver circuit which uses N-channel power MOS FETs in its driver stage.
By employing the power MOS FETs for the output stage, this driver circuit has a substantially improved saturation voltage and power consumption as compared with conventional driver circuits that use bipolar transistors.
In addition, the drive current can be adjusted by an external resistor in a power-saving mode.
The UPD16803 is therefore ideal as the driver circuit of the 2-phase excitation, bipolar-driven stepping motor for the head actuator of an FDD.

FEATURES
• Low ON resistance (sum of ON resistors of top and bottom transistors)
- RON1 = 1.5 W TYP. (VM = 5.0 V)

Description
The VN5025AJ-E is a monolithic device made using STMicroelectronics VIPower technology. It
is intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient
compatibility table). This device integrates an analog current sense which delivers a current
proportional to the load current (according to a known ratio) when CS_DIS is driven low or left
open. When CS_DIS is driven high, the CURRENT SENSE pin is in a high impedance
condition. Output current limitation protects the device in overload condition. In case of long
overload duration, the device limits the dissipated power to safe level up to thermal shut-down
intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as fault condition disappears.
