ADN2813 datasheet


Description :

The ADN2813 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 10 Mb/s to 1.25 Gb/s. The ADN2813 automati-cally locks to all data rates without the need for an external reference clock or programming.


1. Serial data input: 12.3 Mb/s to 1.25 Gb/s
2. Exceeds SONET requirements for jitter transfer/generation/tolerance
3. Quantizer sensitivity: 6 mV typical
4. Adjustable slice level: ±100 mV
5. Patented clock recovery architecture
6. Loss of signal (LOS) detect range: 3 mV to 15 mV
7. Independent slice level adjust and LOS detector
8. No reference clock required
9. Loss of lock indicator
10. I2C interface to access optional features
11. Single-supply operation: 3.3 V
12. Low power: 350 mW typical


ADN2813 pinout


1. SONET OC-1/-3/-12 and all associated FEC rates
2. Fibre Channel, GbE, HDTVs
3. WDM transponders
4. Regenerators/repeaters
5. Test equipment
6. Broadband cross-connects and routers

W85C178 Datasheet PDF – Real Time Clock IC

Part Number : W85C178

Function : Real Time Clock With 128-Byte RAM

Package : DIP 24P

Manufacturers : Winbond


W85C178 Real Time Clock

Description :

The Real Time Clock with 128-byte RAM is a peripheral device for use with various microprocessors. The W85C178 is designed to be a direct replacement for the MC146818A. The device’s function include a time-of-day clock, an alarm, a one-hundred-year calendar, a square wave generator, programmable interrupts, and 114 bytes of nonvolatile static RAM. The device uses CMOS technology and interfaces with most microprocessor buses. The device consumes very little power.

Pinouts :
