Renesas ICS853P022AGLF

Overview

ICS853P022AG from Integrated Circuit Systems is a dual-channel LVCMOS/LVTTL-to-differential 3.3V LVPECL clock translator with 1.1GHz maximum output frequency, 320ps typical propagation delay, and 0.03ps RMS additive phase jitter. It operates from 3.0V–3.8V VCC (VEE = 0V) and supports industrial temperature range (–40°C to +85°C), serving as a timing interface in high-speed serial link clock distribution.

For engineers reviewing the ICS853P022AG datasheet, ICS853P022AG pinout, ICS853P022AG application, or ICS853P022AG equivalent, key selection criteria include differential LVPECL output drive capability, part-to-part skew ≤650ps, single-ended input compatibility with LVCMOS/LVTTL logic families, and TSSOP-8/G-package thermal performance under 3.3V supply conditions.

Technical Context

The ICS853P022AG implements two independent translation channels, each accepting single-ended LVCMOS/LVTTL clock inputs (D0, D1) and generating complementary LVPECL outputs (Q0/nQ0, Q1/nQ1). Its internal circuitry includes level-shifting buffers optimized for low-skew, high-frequency operation without external PLLs or feedback loops.

It supports dual supply modes: LVPECL mode (VCC = 3.0V–3.8V, VEE = 0V) and ECL mode (VCC = 0V, VEE = –3.8V to –3.0V), with verified DC output voltage ranges of VOH = 2.25V–2.33V and VOL = 1.36V–1.53V (LVPECL mode, VCC = 3.3V). Output rise/fall times are specified at 25%–75% of swing, measured into 50Ω loads.

FAQ

What supply voltage configuration does ICS853P022AG require for LVPECL operation?

The ICS853P022AG requires VCC = 3.0V to 3.8V and VEE = 0V for LVPECL mode operation. This single positive supply simplifies power design compared to traditional ECL translators. The device draws up to 35mA from VCC under worst-case conditions, and proper 0.1µF ceramic decoupling near pin 8 is mandatory for stable output waveform integrity in the ICS853P022AG.

Does ICS853P022AG support both LVCMOS and LVTTL input logic levels?

Yes, the ICS853P022AG accepts both LVCMOS and LVTTL input levels on pins D0 and D1. Its input threshold specifications-VIH ≥ 2.0V and VIL ≤ 0.8V at VCC = 3.3V-are compatible with standard 3.3V logic families. No external biasing or termination resistors are needed, making the ICS853P022AG directly interoperable with FPGAs, microcontrollers, and clock generators using either interface standard.

What is the maximum guaranteed output frequency for ICS853P022AG?

The ICS853P022AG guarantees operation up to 1.1GHz across the full industrial temperature range (–40°C to +85°C). This specification is validated per Table 3 AC Characteristics and applies to both output pairs (Q0/nQ0 and Q1/nQ1) under LVPECL mode with proper 50Ω load termination. Signal integrity beyond this frequency depends on PCB layout, termination accuracy, and source drive strength-not the ICS853P022AG itself.

How is output skew managed between the two channels of ICS853P022AG?

The ICS853P022AG specifies part-to-part skew ≤650ps maximum and output-to-output skew ≤210ps maximum (per Table 3). These values are measured under identical supply, temperature, and loading conditions. To achieve guaranteed skew performance, designers must match trace lengths for both output pairs and maintain consistent termination-critical for applications like dual-lane SerDes where inter-lane timing alignment affects link training success in the ICS853P022AG.

Is ICS853P022AG pin-compatible with any industry-standard alternatives?

Yes, the ICS853P022AG is pin-compatible with the MC100EPT22 in 8-pin SOIC (M-suffix) and TSSOP (G-suffix) packages. However, the MC100EPT22 operates exclusively in ECL mode (negative supply), whereas the ICS853P022AG supports both LVPECL and ECL modes. This makes the ICS853P022AG a functional upgrade for designs migrating from MC100EPT22 where 3.3V-only operation is desired-without PCB redesign.
