PROGRAMMABLE DELAY CHIP WITH ANALOG INPUT SY10E196 SY100E196 DESCRIPTION FEATURES ■ Up to 2ns delay range ■ Extended 100E VEE range of –4.2V to –5.5V ■ ■ ■ ■ ■ ■ ■ Precision Edge® SY10E196 Precision SY100E196 Edge® The SY10/100E196 are programmable delay chips (PDCs) designed primarily for very accurate differential ECL input edge placement applications. The delay section consists of a chain of gates and a linear ramp delay adjustment organized as shown in the logic diagram. The first two delay elements feature gates that have been modified to have delays 1.25 and 1.5 times the basic gate delay of approximately 80ps. These two elements provide the E196 with a digitally-selectable resolution of approximately 20ps. The required device delay is selected by the seven address inputs D[0:6], which are latched on-chip by a high signal on the latch enable (LEN) control. If the LEN signal is either LOW or left floating, then the latch is transparent. The FTUNE input takes an analog coltage and applies it to an internal linear ramp for reducing the 20s resolution still further. The FTUNE input is what differentiates the E196 from the E195. An eighth latched input, D7, is provided for cascading multiple PDCs for increased programmable range. The cascade logic allows full control of multiple PDCs, at the expense of only a single added line to the data bus for each additional PDC, without the need for any external gating. ≈20ps digital step resolution Linear input for tighter resolution >1GHz bandwidth On-chip cascade circuitry 75KkΩ input pulldown resistor Fully compatible with Motorola MC10E/100E196 Available in 28-pin PLCC package PIN NAMES Pin M9999-032006 hbwhelp@micrel.com or (408) 955-1690 Function IN/IN Signal Input EN Input Enable D[0:7] Mux Select Inputs Q/Q Signal Output LEN Latch Enable SET MIN Minimum Delay Set SET MAX Maximum Delay Set CASCADE Cascade Signal FTUNE Linear Voltage Input VCCO VCC to Output Rev.: H 1 Amendment: /0 Issue Date: March 2006 Precison Edge® SY10E196 SY100E196 Micrel, Inc.
