AD8145YCPZ-RL

Overview

The AD8145YCPZ-RL is a triple differential-to-single-ended receiver designed for high-speed analog signal and video transmission. It features a 500 MHz bandwidth, 2000 V/µs slew rate, and 69 dB common-mode rejection at 10 MHz. The device operates on supply voltages from 4.5 V to 11 V with a quiescent current of approximately 48.5 mA. It includes two auxiliary comparators with hysteresis for sync decoding and supports gain configurations of 1 or 2 via internal resistors.

Feature Summary

• Triple active feedback architecture optimized for RGB and YPbPr video reception over twisted pair cables
• Integrated dual comparators with hysteresis for digital signal reception and video synchronization extraction
• Configurable closed-loop gain of 1 or 2 using on-chip resistors and external reference connections
• High differential input impedance of 1 MΩ with wide common-mode voltage range

Applications

• RGB video receivers for component video signals
• YPbPr video receivers for high-definition video transmission
• Keyboard, Video, Mouse (KVM) switch systems
• Unshielded twisted pair (UTP) cable receivers in noisy environments

Procurement Notes

Verify the specific suffix YCPZ-R7 against the manufacturer's ordering guide to confirm package type, temperature grade, and reel quantity specifications. Ensure compatibility with the required operating temperature range and power supply constraints defined in the datasheet. Cross-reference pinout requirements for the 32-lead LFCSP package during integration planning.

Selection Notes

Select this component for applications requiring differential-to-single-ended conversion with high common-mode rejection. Consider the AD8145W variant if automotive qualification under AEC-Q100 standards is required. Evaluate the need for the integrated comparators; if unused, note that they require a positive supply greater than 4.5 V, whereas amplifiers can operate with split supplies as low as ±2.5 V.

Part Context

The AD8145 belongs to Analog Devices' family of high-speed video receivers. It is often paired with differential drivers like the AD8133 or AD8134 to form complete transmission solutions over Category 5 UTP cables. The device utilizes an active feedback architecture distinct from conventional operational amplifiers, providing balanced inputs and independent feedback paths to maintain performance.

Replacement Considerations
